这是关于turbo码的编解码的几个matlab程序,希望大家能用的上!(This is a turbo code on several matlab codec procedures, hope that we can use the on!)

北京邮电大学的通信MATLAB仿真跟大家分享下(Beijing University of Posts and Communications MATLAB simulation share with you the next)

行列式阶次辨识在白噪声的情况下通过计算DR的值得到最终的结果。(The order identification of the determinant in the case of white noise by calculating the DR' s worth to the final result.)

This is a matlab software package for butterworth band pass filter design. you could change the high pass and low pass frequency to design the betterworth filter.

本文在介绍MIMO无线通信系统模型的基础上，通过对比分析几种常用空时编码方法，选定空时分组码对信号进行编码并建立瑞利衰落信道模型，通过对两发一收及两发两收系统的仿真，研究接收天线数对系统接收信号可靠性的影响。之后进一步扩展到不同发射矩阵条件下研究多发一收系统的频谱利用率及误符号率，分析不同天线数目，不同发射矩阵条件下空时正交分组码检测算法的性能。(This paper introduced the MIMO wireless communication system model, through the comparative analysis of several commonly used method of space-time coding, grouping code for the selected space-time signal is encoded and establish Rayleigh fading channel model, through two rounds one and two rounds of closing Simulation of two closed systems, research receiving antennas to receive signals affect the reliability of the system. After further extended to study the conditions under different emission matrix of multiple spectral efficiency and symbol error rate of a closed system, analyze the different number of antennas, the performance under different emission matrix orthogonal space-time block codes condition detection algorithm.)
