Client block and method for using it in a wireless communication system / 2313176
In the method, signal of first channel is modulated with usage of first short Walsh code, modulated signal of second channel is added to control signal, total signal and modulated signal of first channel are multiplied by complex pseudo-noise code. Usage of short orthogonal codes ensures suppression of mutual interferences, which is inherent in ground-based wireless systems. A set of sub-channel codes is formed using four mutually orthogonal short Walsh codes, but usage of longer codes is acceptable. It is preferred that control data is transferred through first transmission channel, and power control data is transferred through second transmission channel. Length, and number of elements, in each channel code may be different, to additionally reduce ratio of peak transmission power to average transmission power during transmission at higher speeds.
