Viterbi Algorithm based frequency offset estimation for GMSK
A new nondata-aided frequency offset estimation method has been proposed for GMSK which is based on viterbi algorithm to remove the information phase of the complex envelope signal. It has wide frequency offset estimation range, and its feedforward structure made itself simple digital implementation. Its complexity would be controlled by the viterbi algorithm parameter. Simulation results have shown the validity of the algorithm in frequency offset estimation. At last, the normalized mean square errors (MSE) performance of the algorithm has also been proposed in additive white Gaussian noise channel
