使用Matlab的M语言写的基带AMI编码程序-exam3_ami

本程序介绍了LTE中信道的基于导频的信道估计，方法经典，值得学习一下(This program introduces the LTE CITIC Road Pilot-based channel estimation, the classical method, it is worth learning about)

说明：  离散余弦变换,实现数据的压缩以及相应噪声的去除(Discrete cosine transform, data compression and noise removal of the corresponding)

数字信号处理中的基于Monte Carlo的方法(Monte Carlo-based methods in signal processing)

The BCJR algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises (principally convolutional codes). The algorithm is named after its inventors: Bahl, Cocke, Jelinek and Raviv.[1] This algorithm is critical to modern iteratively-decoded error-correcting codes including turbo codes and low-density parity-check codes.

说明：  扩频与解扩仿真实验，用matlab可以完全实现，图形也正确(The simulation experiment of spread spectrum and despreading can be realized by MATLAB, and the graph is correct)
