Abstract

The research studies the carrier and timing synchronization algorithms in all-digital communication receivers. According to the optimal estimation theory of carrier phase and symbol timing synchronization technology, the estimation algorithm of the maximum likelihood carrier phases is proposed and used in computer simulations. The simulation results reveal that when the signal-noise ratio (SNR) and the observation length L meet certain requirements, the curve is highly smooth and symmetric. The allowable minimum observation length is the capture length under this condition. If the SNR is larger than 10 dB, as for 16QAM signals, the synchronized algorithm for maximum likelihood carrier phase can track phases within 16 symbols.
