Abstract
When 32-ary amplitude phase shift keying (32APSK) modulation is used in the communication system, carrier recovery is one of the most important technology. The decision-directed (DD) phase locked loop (PLL) is widely used for carrier recovery. Based on the decision-directed (DD) phase locked loop (PLL) algorithm, the paper proposes a new fine carrier phase recovery method, which is based on the constellation classification and different nonlinear operation. Simulation results show that the performance of the proposed method is much better than the traditional one.
