这是矩阵计算一书的第二部分，由于是从网上下载的，两部分是分开的，没法合并，所以只好分两次上传，欢迎下载浏览。(This is the matrix of the second part of the book, as it is downloaded from the Internet, the two parts are separated, can not be combined, so only two upload, please download the browser.)

GPRS fundamental review

大规模MIMO信道容量分析，主要分析了BS和MS天线数不断增大时，对信道容量的影响。(The analysis to Massive MIMO channel capacity as the antennas of BS and MS grow up. )

Dynamic Subchannel and Bit Allocation in multiuser mimo-ofdma systems.

实现ls信道估计，计算误码率计算，均方误差，对比MMSE和ls两种算法(ls estimation ababababababbababababaa)

说明：  卷积神经网络，可以很好的实现文本分类或者图像识别(Convolutional Neural Networks)

MIMO指多输入多输出，MIMO技术大致可以分为两类：发射/接收分集和空间复用。传统的多天线被用来增加分集度从而克服信道衰落，具有相同信息的信号通过不同的路径被发送出去，在接收机端可以获得数据符号多个独立衰落的复制品，从而获得更高的接收可靠性。这种技术往往要结合多天线技术，而多天线技术在移动通信中得到了广泛的研究。(MIMO refers to Multiple Input Multiple Output, MIMO technology can be broadly classified into two categories: transmit/receive diversity and spatial multiplexing. Traditional multi-antenna was used to increase the degree of diversity to overcome channel fading, the signal with the same information through different paths have been sent in the receiver-side data symbols can be multiple independent copies of the decline, which was higher reception reliability. This technology often have to combine multi-antenna technology, and multi-antenna technology in mobile communication has been widely studied.)
