DOFmodel

An article very useful to perform Galois field computations

一个配对的RLS程序，和先前上传的程序对比起来看(A pair of RLS procedures, and previous procedures Upload contrast look)

将要分析的数据放在C盘的ELI.xls表的Bay表单中，根据数据多少调整读取范围（修改 b2:f16 此句) 结果有两种，一种是按数据计算权值求出的结果，另一种是参考建议值求出的结果。结果写入C盘的ELI表格，范围要手动根据数据多少调整(The data will be analyzed on the C disk ELI.xls Table Bay form, how much to adjust the data read range (change ' b2: f16' sentence) result, there are two, one is calculated according to weight data the results obtained, the other is the result of reference to find the recommended value. Results written to C drive of the ELI forms, the scope of how much to manually adjust the data)

用matlab写的的循环码编解码程序，同时还有系统仿真的性能分析(Matlab write the loop encoding and decoding procedures, as well as system simulation and performance analysis)

程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)
