通过分析8PSK 调制方式的载波恢复、定时恢复算法, 提出了一种适用于新一代数字卫星电视标准DVB S2
的全数字解调算法, 改进了相位频率检测( PFD) 算法以适合于8PSK 解调. 载波恢复采用频率检测( FD) 和相位频率
检测相结合的结构, 跟踪范围超过1 倍符号率. 采用Gardner TED 算法进行定时恢复.-By analyzing the 8PSK modulation carrier recovery, timing recovery algorithm is proposed for a new generation of digital television standard DVB S2 Satellite all-digital demodulation algorithm, improved phase-frequency detector (PFD) algorithm for 8PSK demodulation . carrier recovery using frequency detection (FD) and phase-frequency detector combined structure, tracking more than 100 times the symbol rate range. using Gardner TED algorithm timing recovery.
