摘要

This paper analyzes the performance of prerake techniques, which is proposed for the time-division duplex (TDD) code-division multiple-access (CDMA) systems, based on quarter phase-shift keying (QPSK) modulation. From the results we find that QPSK has the advantage of stability over BPSK while both of them have the same averaged bit error rate (BER). This advantage, together with the superiority over rake receiver of moving the circuitry from the mobile unit (MU) to the base station (BS), makes the prerake technique useful in TDD systems.
