Paper Abstract

A union carrier synchronization scheme of feed-forward frequency offset estimation and PLL for OQPSK signals is discussed in this paper. A feed-forward frequency offset estimator is developed based on the cyclic spectrum of the received signal. In order to suppress channel noise, an improved strategy is proposed. Simulations show that the presented scheme can achieve steady state much more quickly than conventional Costas loop. At the same time, the steady error of the union scheme is also smaller.
