    摘要： A CDMA receiving apparatus receives a direct sequence CDMA signal produced through QPSK spreading modulation, performs coherent detection of the direct sequence CDMA signal, and despreads the signals, obtained through the coherent detection, through a despreading portion. The despreading portion comprises a selector portion. The selector portion selects signals as a demodulated and despread in-phase output signal and a demodulated and despread quadrature output signal, in accordance with despreading codes, from demodulated in-phase and quadrature signals obtained through the coherent detection, and an inverted in-phase and quadrature signals obtained as a result of the signs of the demodulated in-phase and quadrature signals being inverted.

    摘要： An A/D converted and inputted signal is stored in a memory. A sliding correlator sequentially reads the signal stored in the memory and despreads this signal. A despreading timing is adjusted and then the candidate for a despreading code is outputted from a code generation circuit. The despreading code outputted at a predetermined timing is used for obtaining a correlation value of signals outputted from the memory, using the sliding correlator. Thus, by storing signals in the memory, fluctuation of a correlation value caused by fading does not occur while specifying a code or detecting a despreading timing.
