很好的算法，很好的程序，能够实现最小信道的确定(It s a good code ,and it s a good program ,it can make something true )

基于互相关函数，采用求和广义互相关函数(summed-GCC)法用于机器人系统平台。由于采用不同的映射函数(mapping functions)，GCC法在该平台下，只需三个麦克风即可进行三维定位，突破了基于TDOA法进行三维声源定位最少需4个麦克风的限制(Based on cross-correlation function, using generalized cross-correlation function sum (summed-GCC) method for the robot system platform. Because of using different mapping function (mapping functions), GCC method in the platform, the only three to three-dimensional microphone positioning, a breakthrough TDOA method based on three-dimensional sound localization will take at least four microphone restrictions)

无线通信类的，适用于自适应调制算法，用户算法(AMC algorithm)

说明：  CCSDS推荐的LDPC编码方案，一系列参考标准，很好哦！(CCSDS recommended LDPC coding scheme, a series of reference standards, very good!)

BPSK的扩频和调制的matlab程序，其中扩频码为m序列，包含产生m序列的matlab程序。(BPSK spread spectrum modulation matlab program, the spreading code of m-sequence contains sequence matlab program generates m.)

这是一个用matlab软件仿真移动通信小区的模型，简单建立25个小区，并截取其中一个三角形小区当做软切换的环境。(This is a matlab software simulation model of the mobile communication cell, simple establishment of 25 plots, and the interception of which a triangular plot as a soft switching environment.)

ofdm的编码过程，用evm和比特率进行对比(The encoding process of OFDM is compared with EVM and bit rate)

将ADC对输入端口电压的转换结果按转换数据和对应的模拟电压的形式通过串口发送到PC机屏幕上显示(The ADC input port voltage conversion results by converting data and the corresponding analog voltage sent to the PC via the serial port on the screen)
