Joint frequency and timing recovery for MSK-type modulation

We investigate a novel nondata-aided method for jointly estimating timing a nd carrier frequency offset in MSK-type modulation. The algorithm has a fee dforward structure and Lends itself to a simple digital implementation, Its estimation accuracy depends on a design parameter that may be varied to tr ade performance for computational complexity. Setting the parameter to unit y yields a synchronization scheme already known in the literature. Computer simulations are used to assess the synchronizer performance on AWGN Raylei gh fading channels with MSK and Gaussian MSK modulation.
