基于FPGA的Link11解调实现

Demodulation Implementation of Link11 Based on FPGA

首先介绍Link11数据链的信号特征形式,给出一种Link11的解调算法,基于MATLAB仿真分析证明能够对Link11数据链信号进行有效解调;之后将此解调算法采用FPGA实现;运行结果表明,解调算法基于FPGA实现可行,且资源消耗相对较少。

Firstly,the character form of then Link11 is introduced,and a kind of demodulation algorithm of the Link11 is showed,and based on MATLAB simulation analysis,proved that demodulation algorithm can effectively demodulate the Link11 TADIL signal.Then using the FPGA realizes that demodulation algorithm.Indicated by the running on the FPGA chip,Demodulation algorithm based on the FPGA is feasible,and the resource of the FPGA taking up is lower comparatively.
