A Joint GMSK Phase and Timing Synchronization Algorithm suitable for software radio

摘要

A new none data-aided (NDA) and all-digital algorithm is proposed for joint estimation of timing and carrier phase in GMSK modulation. It is based on maximum-likelihood arguments and has a feed forward structure. The proposed algorithm is also suitable for linear software radio. Performance in AWGN channel is assessed by computer simulation, and is compared with the modified Cramer-Rao bound and other existing algorithms.
