FIELD: radio communication. SUBSTANCE: new architecture of signal processing for base stations and interface stations employed in communication system with spectrum expansion simplifies data transmission, decreases carrying capacity of buses and does not require special synchronization of signals which should be integrated. Series of transmission modules is utilized to transmit data to proper analog transmitters employed to form communication circuits for each subscriber's system. Each transmitting module uses number of encoders and modulators to form communication signals with expanded spectrum employing corresponding pseudorandom noise expansion codes. Communication signals with expended spectrum for each transmitting module for each subscriber D of system are summed up and are sent to single analog transmitter coupled to this module. Signals subject to integration are automatically synchronized with common synchronization signals used for elements within limits of each transmitting module. Number of processing elements in each module is such that at least one processing path is accessible per each subscriber or subscriber channel over which it is desirable to transmit information through connected analog transmitter. Data are extracted from modules at substantially reduced rates of data transmission which can be easily adapted utilizing known technology. It is very useful for satellite communication systems or cellular communication systems with high carrying capability. Said system architecture can be profitably implemented with use of series of easily manufactured circuit modules which achievable technical result of invention. EFFECT: profitable implementation of proposed architecture. 18 cl, 6 dwg
