网络相干载波恢复

Carrier recovery is the key technology for coherent demodulation receiver in RF communication, and carrier recovery algorithm directly determiner the performance of the receiver.
载波恢复技术是无线电射频（RF）通信中相干解调接收机不可缺少的关键技术之一。
Bit error rate compared with coherent detection, it is more appropriate and robust to the situation when the carrier recovery is difficult.
3误比特率时性能损失约为2dB，但它对载波恢复困难的情形更为合适和稳健。
Consider the ROF link characteristics of the digital coherent receiver compensation algorithm, we were focusing on research and build a simulation platform for the frequency locking and phase recovery, linear demodulation, carrier recovery algorithm with theoretical analysis and simulation shows.
考虑ROF链路特点，研究数字相干接收机内的补偿算法，重点研究并搭建仿真平台对频率锁定与相位恢复、线性解调、载波恢复等算法进行理论推导和仿真证明。
