Brief description of drawings

Goals and features MCV/AM system of simultaneous transmission in accordance with the present invention will be apparent from the following description of a variant example of its implementation, together with the attached drawings, in which

figure 1 shows the generator AM signal simultaneous broadcast radio in accordance with the present invention, and

figure 2 shows the spectrum of the signal of simultaneous transmission, in accordance with the present invention.

Detailed description of the invention

In accordance with the present invention the digital and analog signals are combined in one channel. To avoid distortion of the digital system, the digital modulated signal to pass one side band channel bandwidth that allows you to perform demodulation without distortion of the digital modulated signal at the receiver.

In addition, the simultaneous signal transmission provides backward compatibility with existing AM a PA system broadcasts, since the envelope signal simultaneous transmission perfectly represents the analog signal. In accordance with the present invention, the backward compatibility of the signal at the same time the transmission is provided by modulation of the demodulated sideband AM channel correction signal Sspects signal simultaneous transmission in accordance with the present invention shown in figure 2. The upper side band transmission channel contains a digital modulated signal, such as signal MCV, and the lower side bandwidth contains a correction signal C. In the center of both side bands added to the carrier so that could be the result of simultaneous signal transmission. Of course, it is also possible that the digital modulated signal was transmitted in the lower side of the channel bandwidth, and correcting the signal was transmitted in its upper side band transmission.

When demodulation signal envelope simultaneous transmission in accordance with the present invention receive undistorted analog audio signal with full audio bandwidth. In the case of a channel width of 10 kHz bandwidth analog audio signal is 5 kHz. Therefore, the bandwidth of the sound does not change when the simultaneous transmission of signals in accordance with the present invention.

The audio signal includes distortion only in the case of the distortion channel, or distortion of frequency characteristics of an analog AM/FC of the filter, i.e. in the case of a receiver with low quality, asymmetric response of the filter the if (intermediate frequency).

The analog signal does not create an obstacle to the modulated digital signal MCV.

Generating a corrective signal,preferably, during the iterative process. This iterative method allows you to modulate the signal MCV in the upper side of the passband and the analog signal in the lower sidewall of the bandwidth, or Vice versa. In addition, in the center of both side bandwidths add a carrier to obtain an estimate of the simultaneous signal transmission. A full assessment of simultaneous transmission signal containing the upper sideband EBP (USB), lower sideband NBP (LSB) and a carrier, demodulateur the envelope demodulator. After that, the analog signal from the demodulated envelope is subtracted from the analog signal to obtain the error signal. The error signal is then weighed with a constant k before the next stage to the analog signal will be added to the error signal to obtain a new estimate of the signal NBP representing an analog audio signal. This iteration is repeated N times until it receives an adjustment signal, and the signal of simultaneous transmission in accordance with the present invention will not be generated and sent.

The constant k may also be variable, depending on the amplitude of the analog signal and/or digital signal and/or signal errors.

Figure 1 shows an example of a generator AM signal simultaneous broadcast radio in accordance with the preferred VA what Ianto implementation of the present invention. The signal simultaneous broadcast radio in accordance with the present invention generate the first modulator 1, which modulates the digital signal transmission in one side bandwidth carrier of the transmission channel, here in the upper side bandwidth EBP, and the second modulator 2, which modulates the corrective signal With the second side bandwidth carrier of the transmission channel, here in the lower side of the passband of the NBP.

Next, to generate a signal simultaneous broadcasts in accordance with the present invention, the first adder 3 summarizes these both sidebands and possibly the carrier signal in the center of both side bands and the carrier signal generated by the generator 4 of the carrier signal.

Digital transmission signals are transmitted in the first modulator 1 corresponds to the time adjustment signal, that is, delayed for generating a corrective signal to ensure compliance with them.

In addition, the signal generator translational radio in accordance with the present invention, which is shown in figure 1, comprises a generator corrective signal, which, in this case, also delays the digital signal. The oscillator adjustment signal includes a third modulator 5, which is designed to modulate pointed to by the th digital signal transmission in a specified one side bandwidth, that is, here in the upper side of the passband, the fourth modulator 6, which is designed to modulate the analog signal transmission in the other side bandwidth, here in the lower side of the passband, the second adder 7, intended to summarize the above both of the side bands and the carrier signal, which is generated by the second generator 8 of the carrier signal, in the centre of the listed both side bands. Further, the oscillator adjustment signal contains the first demodulator 9 envelope, intended for demodulation generated in this way simultaneous transmission signal, the first delay element 10 that is designed to delay the analog signal transmission, in accordance with the processing time to generate a corresponding demodulated signal synchronous transmission, the first myCitadel 11, designed to generate the error signal by subtracting the envelope of the demodulated signal simultaneous transmission of the delayed analog signal transmission, the first multiplier 12, designed for weighing error signal with time-varying and not time-varying variable, the third adder 13, which is designed to generate a corrective signal or interim corrective signal by summing weighted what about the error signal with the delayed analog signal transmission, and the second delay element that is designed to delay the digital signal transmission, in accordance with the processing time required for generation and demodulation of the corresponding simultaneous signal transmission.

As indicated above, these elements of the oscillator adjustment signal, which can be considered as one unit corrective signal, generates an adjustment signal or an intermediate correcting signal. The correction signal generated by this module corrective signal usually represents only a rough estimate and does not necessarily provide adequate transmission of analog signal transmission. However, its quality can also be considered sufficient. When quality cannot be considered sufficient, the resulting signal from the third adder 13, can be treated in a similar manner as the analog signal has been processed previously, using N similar to the following modules of the correction signal. In this case, the digital signal transmission will also be correspondingly delayed.

SUBSTANCE: invention concerns digital broadband data transfer systems, particularly decoding of frame error correction of multiple-protocol encapsulation (MPE-FEC) in handheld digital video broadcasting system (DVB-H). Invention claims method and device for MPE-FEC frame decoding in DVB-H. Filtration of packet identification (PID) is performed in TS packet received over wireless network to identify TS packet, and table ID is detected by data heading information intended for identification of section data type. If section data are MPE section, then the frame is buffered. If after IP datagram storage for last MPE section some part remains in data area, then remaining part is augmented with zeros. If section data are MPE-FEC section, then frame is buffered based on parity data obtained from MPE-FEC section.

EFFECT: efficient method of MPE-FEC frame decoding in handheld DVB-H for reception of transport stream (TS) packet and Internet protocol (IP) datagram reconstruction.
