Nonlinear filtering of pseudonoise signals using high-order Markov chain model

摘要

The problem to be considered in this paper is code synchronization in data communication systems using pseudonoise (PN) signals based on linear feedback shift register (LFSR) sequences. A novel non-linear filtering algorithm for such systems that uses high-order Markov chain for signal representation is proposed. This algorithm shows the ability to reduce PN signal synchronization time.
