CDMA MOBILE COMMUNICATIONS SYSTEM AND METHOD WITH IMPROVED CHANNEL ESTIMATION AND PILOT SYMBOL TRANSMISSION

摘要

The present invention is an improved system and method for transmitting and receiving digital information over mobile communication channels. The present invention includes an enhanced channel estimator (34) which iteratively estimates channel amplitude and phase distortion from received pilot and data signal information at various time instants. The iterative channel estimation scheme of the present invention provides increased performance of the transceiver system which allows for efficiencies such as transmission of a minimal amount of pilot information and reduction in the transmitted power.
