Methods, devices and systems of signals receiving and decoding in the presence of noise using the shears and deformation

FIELD: radio engineering, communication.

SUBSTANCE: receiving method includes the signal receiving and discretization in which the data package is encoded. The shear is generated and stored by means of the controller, containing the pair of values for each of the signal selection specified number. The detected package from the stored shears is decoded. The filter is formed from the shears plurality by its integration by means of the controller, it has the set bandwidth. The average frequency of the filter is reset from the first medium frequency to the second medium frequency by deformation of the stored shears, from which the filter is formed by turning the corresponding pairs of its values by the certain amount.

EFFECT: increase of the received signal detection and decoding efficiency.

FIELD: physics; image processing.

SUBSTANCE: present invention relates to television and can be used in making application systems, and particularly for space-time processing images. Proposed is a device for space-time processing images based on matrices of photosensitive charge-coupled devices, which also comprises the following: beam splitting system, second obturator, mutual displacement device and a device for measuring level of illumination, providing for conversion of the average level of illumination of the projected image into an electrical signal for adapting the device to changes in viewing conditions. The device for measuring level of illumination can be a semiconductor photoelectric transducer, which converts the projected light flux into an electrical signal, the level of which is proportional to the average illumination. In accordance with the signal level at the output of the device for measuring level of illumination, the processing device is adapted viewing conditions.

EFFECT: space-time processing of images simultaneously with its creation while providing for adaptation to the level of illumination and prevention of distortions of the processing results, related to overfilling of potential wells of the matrix of the photosensitive charge-coupled device.
