REDUCED GAIN SPREAD SPECTRUM COMMUNICATION SYSTEM AND METHOD

摘要

A reduced gain spread spectrum communication system and a method therefor are provided to allow real-time transmission of voices in a multi-user environment by sufficiently reducing a packet transmission time. A spreading unit(28) includes an input part and an output part, receives a digitized voice signal from the input part and spreads it by using a voice spreading sequence length smaller than a spread gain available for a certain transmission bandwidth to generate a voice spread signal. In addition, the spreading unit(28) receives a data signal from the input part and spreads it by using a data spreading sequence length greater than the voice spreading sequence length to generate a data spread signal. A transmitter transmits the voice spread signal.
