Abstract

To simplify the structure of the demodulator and reduce the hardware scale in a code division multiple accessing communication apparatus. A plurality of base band received signals are multiplexed in a time division manner, so that one matched filter executes path searching or a time division multiplexing processing is executed for demodulation in a despreader. Or path searching and demodulation for a plurality of codes are executed with time division multiplexing of outputs from a plurality of code generators.
