PURPOSE:To provide a parallel transmission direct spread spectrum communication equipment capable of suppressing the influence of noise and the increase of a hardware scale accompanying the increase of a parallel transmission number. CONSTITUTION:A transmission high-seed digital data series is divided into (n) data series by a demultiplexer 2 and distributed components generated from a carrier wave generation circuit 101 and distributed into (n) pieces by a carrier wave distribution circuit 102 are respectively PSK modulated by the inputted data series in respective PSK modulators 30a-30n. |
