摘　　要：根据Alamouti编译码工作原理,经Quartus II仿真完成了基于ML译码算法的Alamouti译码器的FPGA设计与实现.通过分析RTL电路图,给出了ML算法的复杂度与进制数M的关系,并利用MATLAB完成相同译码算法下Alamouti传输系统的仿真.对比分析MATLAB与Quartus II下译码输出数据,证明基于FPGA的设计方案能够实现Alamouti译码功能.Base on the principles of Alamouti encoding and decoding and ML decoding algorithm,an Alamouti decoder on FGPAwas designed and realized by Quartus II simulation.The relationship between the complexity of ML algorithm and the number Mof modulator was given by analyzing RTL circuit diagram.The simulation of Alamouti’s system was finished with same decodingalgorithm by using MATLAB.By comparative analysis of the decoding output data of MATLAB and Quartus II,it is proved the design based on FPGA could realize Alamouti decoding function.
