Matlab中用到的部分函数列表，按功能分类(Part of the list of functions used in Matlab, classified by function)

source code in matlab for simulating diffrent noise models

摘要或目录空时网格码实现的完整程序 摘要或目录空时网格码实现的完整程序 (Space Time Trellis Code )

此程序完成MIMO各个自程序的功能，比如编码，信道仿真，信道估计，信噪比计算等，各子程序能够独立运行，具有很好的参考价值(This procedure since the completion of all procedures MIMO features, such as coding, channel simulation, channel estimation, signal to noise ratio calculation, the subroutine can be run independently, with a very good reference value)
