摘要： A transmitter of a spread spectrum communication system includes a data generating portion, a differential coding portion, an S/P converting portion, multipliers, PN generator, a local signal generator, modulators, delay elements, combiner, a frequency converting portion, a power amplifying portion and a transmission antenna. Parallel signals are multiplied by a spread code from the PN generator, and the results are delayed by delay elements and multiplexed. Time difference between the delay times are set to an arbitrarily time period of at least 1 chip from each other. Therefore, error rate characteristics can be improved, and degradation of correlated output is suppressed, whereby difficulty in demodulation can be avoided.

摘要： To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels.
