摘要：
A scheme for channel impulse response estimation is proposed for next generation DS/CDMA systems where a pilot channel is simultaneously transmitted with a traffic channel in the reverse link. Through analysis and simulation, the proposed scheme is found to significantly improve channel estimation accuracy and BER performance.
