System and method for CDMA communications |
摘要 |
A system and method for spread spectrum communication primarily for use in mobile CDMA communication systems. The system receiver has simplified architecture, comprising a channel compensator and correlation detector. The channel compensator has a channel estimator and signal constructor. In a preferred embodiment, the channel estimator periodically computes the cross-ambiguity function of the transmitted and received pilot signals of the CDMA system using computationally efficient processing algorithms. The signal constructor uses the estimated multipath parameters to construct a new signal on which effects of the multipath channel is considerably mitigated.
