Abstract :
A reduced-complexity timing recovery method for binary continuous-phase frequency shift keying (CPFSK) is presented. The proposed algorithm is based on phase unwrapping and is easy to implement. Theoretical analysis and computer simulation both show that the new algorithm is able to perform close to the theoretical limit given by the modified Cramer-Rao bound (MCRB).
