发明名称 CODE DIVISION MULTIPLEX SIGNAL RECEIVING DEVICE
摘要 <p>In a code division multiple access signal receiving apparatus for demodulating transmit data by subjecting a receive signal to despread processing using a code sequence identical with a spreading-code sequence on a transmitting side, a cross-correlation detector calculates a cross-correlation value, on a per-symbol basis, between a spreading-code sequence for spread-spectrum modulating local-station-addressed transmit data and a spreading-code sequence for spread-spectrum modulating other-station-addressed transmit data; a discriminator discriminates whether the calculated cross-correlation value has exceeded a threshold value; and a switch halts input, to a decoder, of a portion of the receive signal that corresponds to the full interval or partial interval of a symbol where the cross-correlation value exceeds the threshold value. <IMAGE></p>
