Abstract: communication equipment. SUBSTANCE: device has external interface of modulator, which performs convolution of received signals with multiple-beam spreading. Single converting processor, which operates on the basis of time intervals, demodulates each convoluted multiple beam signal. Output signal of converting processor is output to maximal value detector and pipeline processor. Said pipeline processor, which also operates on the basis of time intervals, combines demodulated multiple beam signals and performs their further processing in order to produce soft solution data for decoding interlacing and error correction in interlacing decoder in order to restore received data. In addition device has interlacing encoder, modulator and transmission adder for modulation of data to be transmitted by means of extended spectrum. EFFECT: decreased cost of device for call signal demodulation, simplified design. 32 cl, 13 dwg

Abstract: communication equipment. SUBSTANCE: integral search processor, which is used in modem of extended spectrum communication system, provides buffering of samples of received signals in buffer and uses conversion processor, which uses time sampling and operates in sequential steps with respect to buffer. Search processor achieves step-by-step autonomous search, which is configured by microprocessor, which defines set of search parameters, including group of antennas for search, initial shift and search window width, as well as number of Walsh characters for accumulation of results for each shift. Search processor calculates correlation power for each shift and produces final list of best possible signal spreading tracks, which are detected upon search, in order to use them for extension of demodulation elements. Search is linear and independent from probability of the fact that target signal was sent in any arbitrary time moment. EFFECT: increased functional capabilities. 2 cl, 15 dwg
