源于任务设计的低密奇偶校验信道码研究程序(matlab program for design channel coding)

说明：  旅行商问题，起点与终点为同一点，求最短路径，(MTSPF_GA Fixed Multiple Traveling Salesmen Problem (M-TSP) Genetic Algorithm (GA))

函数通过输入信号序列和函数序号，以及调制解调选择参数来完成扩频调制解调。original_seq是原始输入序列，可能是未调制序列，也可能是调制序列，walsh_num是walsh函数的序号，select选择对输入的序列进行调制还是解调。(function through the input signal sequence and function of the serial number and choice of modulation and demodulation parameters to complete spread spectrum modulation and demodulation. Original_seq is the original input sequence may not be modulated sequence, and may also be modulated sequence, walsh_num walsh function of the serial number, select choice of input sequence modulation or demodulation.)

最新的改进的遗传算法，具有很多的函数，非常好用(Genetic Algorithm)

Program EDFT produce high-resolution N-point DFT for N greater than the length of data vector.

OFDM水声通信系统中的matlab程序仿真(OFDM communication system simulation)

离散傅立叶变换(DFT)及其反变换的实现,有限长序列的循环移位、循环卷积(Discrete Fourier Transform (DFT) and its inverse transform of the realization of the cyclic shift sequence of finite length, circular convolution)

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)
