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： A wireless communication system in which a base station apparatus having a plurality of transmission antennas and one or more terminal apparatuses communicate with each other is provided with at least two methods of a first feedback method and a second feedback method regarding propagation path information at the time of reception. In accordance with a communication condition between the base station apparatus and the terminal apparatus, or the function of the terminal apparatus, the terminal apparatus performs feedback by one of the two methods of the first feedback method and the second feedback method. The base station apparatus performs spatial multiplexing transmission on the basis of the propagation path information that has been fed back. Thus, in a system in which CSI is fed back for MIMO transmission, desired transmission characteristics can be efficiently obtained.
