Q_DSSS
直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)

水声信道的建模
感觉这份代码中最有价值的应该是水声信道的建模，该源码来自美国 Parastoo Qarabaqi, Northeastern University, 2013其次其提供了基于l1范数下PCA处理算法，来对经由水声信道的信号进行处理给出误码率图，启动比较程序需要先使用信道生成函数对信号进行生成。(The most valuable part of this code is the modeling of underwater acoustic channel. Secondly, it provides a PCA processing algorithm based on L1 norm to process the signals passing through the underwater acoustic channel and gives a bit error rate chart. To start the comparison program, the channel generating function is needed to generate the signals first.)

5_Name
数组可以存放5个人的姓名，每个姓名包括first name，middle name和last name，输出姓名时，其中middle name只取大写的首字母，利用索引编写程序，使得用户输入last name后，输出姓名的全称。(array can store the names of five individuals, including the names of each first name, middle name and last name, the name of the output, which only middle name from the first uppercase letter, the use of indexing programming, enabling users to import last name, the name of the generic output.)

MIMO-Wireless-Networks-chapter1-4
翻译版的《MIMO无线网络手册》（第二版），15年11月才出的，费了很大功夫做了电子版，这里只有前四章，针对的是信道部分，讲的很全面细致，对研究这部分的人有很大帮助(Translated version of MIMO Wireless Network Handbook (second edition), November 15 was out, and spent a lot of effort to make the electronic version, there is only the first four chapters, is for part of the channel, said very detailed and thorough , the study of this part of the people are very helpful)
