  • Method and system for data reception with decreased bit error rate
    Patent number: 7773710
    Abstract: A method and system is provided for improving bit error rate (BER) performance in delay spread fading conditions, such as the fading associated with simulcast systems. BER is improved through novel symbol synchronization that comprises oversampling an input signal and filtering the samples to determine a composite symbol sample point that converges toward the center of the signal's effective eye pattern. The composite symbol sample point may be an average of previous composite symbol sample points and an instantaneous sample point determined based on samples from a synchronization field of the signal. The updated composite symbol sample point may be utilized for future sampling of the incoming signal.
