MISO_Capacity
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.)

Jakes衰落信道模型
Jakes提出了基于正弦波叠加法的Jakes仿真模型。Jakes仿真模型是一种确定模型，产生的信号非广义平稳且不具各态历经性，其二阶统计特性与Clarke参考模型也相差较大。(Jakes fading channel model)

Longley-Rice model代码
说明： 经典无线链路预算模型，预测了在自由空间中由地形的非规则性造成的中值传输衰落。该模型适用于频段为20MHz至40GHz、路径长度为1km至2000km的情况。对于给定的传输路径，该计算机程序通过频率、路径长度、极化方向、天线高度、表面绕射率、地面有效半径和地面导电常数等参数可以确定传输损耗的大小。(Classic wireless link budget model, forecasts the in free space caused by terrain of regularity in the value decline.The model is suitable for the frequency of 20 MHZ to 40 GHZ, path length of 1 km to 2000 km.For a given transmission path, this a computer program can calculate the value of the transmission loss by frequency, path length, polarization direction, antenna height, surface diffraction, effective radius of the ground and ground conductivity constant parameters and so on.)
