FIELD: radio communications. ^ SUBSTANCE: in known transmitter with code division of channels (IS-95 standard), new elements are additionally introduced, namely: transmitter circuit additionally features P orthogonal code generators, (N+K+J+1) signal spectrum generator, P channel signal adders, channel group signal adder, and each information channels features a divider, second encoder, interlacing device and second symbol compressor, each call channel features divider, second coder and interlacing device and appropriate connections between them for creation of new signal code structure and of a form of code compression of channels. ^ EFFECT: more than 3 times increased spectral efficiency of communication system. ^ 5 dwg |
