turbocoding in gmsk modulation

实现数字信号调制方式的识别,包括2ask4ask 2fsk4fsk 2psk4psk(identification of modulated digital signal)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

原理：乘同余法产生随机数来生成均匀分布、瑞利分布、正态分布，压缩包包括3个分布的Matlab源代码(Principle: multiplicative congruential method to generate random numbers to generate uniformly distributed ，Rayleigh distribution and normal distribution.This package includes three distribution of Matlab source code.)

matlab软件中有关elman神经网络预测的程序(matlab software procedures elman neural network prediction)

计算循环平稳信号的4累积量的快速算法，希望对大家有所帮助(Cyclostationary signals calculated cumulant 4 fast algorithm, and they hope to help everyone)

通过此程序希望大家对基本的分岔过程有一个感性的认识。(Through this program hope everyone bifurcation of the basic process has a perceptual awareness.)

说明：  国外的CIC补偿滤波器设计文件，非常有用(Abroad, CIC compensation filter design files, very useful)

差分进化算法标准版，应用时可以自行修改，可以达到较好的优化效果(Differential evolution algorithm standard edition，you can change it if you want to use if for self application Can achieve better optimization effect)

用matlab来实现数字信号处理的原程序(using Matlab to digital signal processing to achieve the original program)
