Spread spectrum communication system and transmitter-receiver

摘要: A spread spectrum communication system for performing by superimposing a pseudo noise signal on transmitted signal. The comprises traffic detecting means the of signal, and changing clock frequency in accordance with output from means. may alternatively comprise transmission quality determining received determined In operation, offers improved S/N ratios where is high or low, saves power low high, ensures large margins control precision mobile stations near upper limit system's line capacity.
