This paper deals with the compensation of the self-noise (jitter) in a nondata aided (blind) feedforward symbol timing estimator using two samples per symbol for linearly-modulated waveforms transmitted through AWGN channels. The main contribution of this paper is the derivation of an appropriate prefilter to achieve nearly jitter-free digital blind feedforward timing recovery. Computer simulations illustrate that the proposed prefiltering scheme improves significantly the performance at mid and high SNRs.
