Abstract
A spread spectrum communication method includes the steps of: spread-spectrum-modulating each of a plurality of data signals to be transmitted on the basis of a plurality of coding signals respectively assigned to the data signals, the coding signals comprising M-sequence codes, which have code patterns same to each other and which phases are sequentially shifted from each other; multiplexing the spread-spectrum-modulated signals; transmitting the multiplexed signals through a transmission path; and selectively demodulating desirable one of the transmitted signals by spread-spectrum-demodulating the transmitted signals on the basis of a decoding signal comprising a M-sequence code, which has a code pattern same as that of the coding signals and which phase is variable, and by controlling the phase of the decoding signal to be in synchronization with the phase of the coding signal assigned to the desirable one of the transmitted signals.
