Enhanced digital communications receiver using channel impulse estimates

Abstract

The present invention provides for a receiver that employs integrated symbol timing adjustment and carrier tracking algorithms based on channel impulse response estimates. It uses variable coefficient least mean square tracking during estimation of the transmission channel's impulse response. Maximum likelihood sequence estimation equalization can also be integrated into the system using a non-real time operation that permits and exploits 'time-reversed' equalization to significantly enhance bit-error rate performance and permits implementation of all the functions in a reasonably simple receiver.
