ABSTRACT:
The present invention relates to a spread spectrum communication system in which a PN code p(t) is generated from a PN generator, data d(t) is multiplied by the PN code p(t) by a multiplier, and multiplied output is subjected to BPSK modulation by a BPSK modulating block. The PN code p(t) is subjected to BPSK modulation at BPSK modulating block, the result is delayed by at least 1 chip of the PN code by a delay block, combined with a modulated signal from BPSK modulating block, converted to an RF signal, and then it is transmitted from an antenna. The signal received by an antenna is amplified by RF amplifier block, converted to an intermediate frequency signal by frequency converting block, split into two, one of the split signals is directly applied to a multiplier, the other is delayed by a delay block, and then these two split signals are multiplied by a multiplier and thus data d(t) is demodulated and output.
