<p>In a direct spreading comb-like spectrum communication method of complementary series repetition modulation type, a set of N (N is an integer of 2 or more) self-complementary series is allotted to each user, one of the N self-complementary series is repeated plural times to convert it to a signal having N comb-like frequency spectra which do not overlap with one another, and N complementary series in relation to the self-complementary series are allotted to the N comb-like spectra, thus generating a transmission signal. Therefore, a CDMA communication method is realized in which by reducing to zero the mutual correlation characteristic representing the signal inputted to the station concerned and transmitted to another station, the distant-near problem is solved, the transmission power level control of the transmitter is dispensed with, the system configuration is simplified, and a multipath signal is easily separated.</p> |
