一个用c编的RS编码的程序，采用BERLEKAMP-MASSEY S 算法，输入m,以及信噪比，可得到生成多项式和误码率等。-with a series of RS coding procedures, using BERLEKAMP- MASSEY S algorithm input m, and the signal-to-noise ratio. available generating polynomial and the error rate.

该代码能够实现在多径信道下对QPSK信号做盲均衡，采用的是CMA算法，仿真结果由四部分构成，分别是：均衡前后信号星座图的对比图；均衡后系统的误码率曲线，误差函数的收敛曲线；信道响应。

现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

这是关于数字通信的一些程序,希望对大家有所帮助-This is the digital communication on some of the procedures, we hope to help
