Title: Code multiplex communication equipment
Inventor: MATSUI HITOSHI
IPC: H04B1/711
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a code multiplex communication equipment in which autocorrelation distortion is eliminated with a simple configuration, deterioration in signal discrimination capability is prevented, number of multiplexing stages is increased, and the transmission efficiency is enhanced. SOLUTION: Transmission data distributed by a distributer 101 are subjected to spread spectrum processing at spread spectrum devices 103, 104 by using a spread signal generated by a spread signal generator 102 respectively. Filters 105, 106 have a transfer function with a characteristic reverse of that of autocorrelation distortion caused by a correlation device 112 at a receiver side and filter a signal from each spread device. Filtered signals are sent to the receiver side via a synthesizer 107 and a modulator 108. The receiver side uses the correlation device to take correlation between a reception signal and the spread signal from an inverse spread signal generator 111. Theoretically, no autocorrelation distortion will be generated. Thus, the reception signal is obtained by an equalizer 113 and a coupler 114.
