基于模糊逻辑控制的数字锁相环，用于通信系统中的载波恢复。Digital phase lock loop base on fuzzy logical control, which is used to recover carrier in communication system.-Based on fuzzy logic control of digital phase-locked loop for the communication system in carrier recovery. Digital phase lock loop base on fuzzy logical control, which is used to recover carrier in communication system.

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
