MIMO系统中能效优化方法仿真

压缩感知的方法进行DOA估计。关键字：压缩感知，DOA(DOA estimation by CS)

costas环解调程序，需要的可以参考一下。costas环解调.m(It is a matlab code for demodulation as costas ring .if you are interested in it, you can refer to it.)

FreeModbus_Slave-Master-RTT-STM32-master V1.6

An Energy-Efficient MAC Protocol for Mobile Ad hoc Networks

485通讯程序，有需要的看看啦，哎怎么要20字啊，真是的(IT IS A 485 COMMUNICATION FOR 28335)

bpsk调制matlab代码,仿真验证正确(bpsk modulation)

说明：  OFDM系统仿真 ----比较OFDM系统的IDFT/DFT实现与模拟调制实现仿真代码，其中假设OFDM系统包含8个子载波，fc=1 Hz，子载波频率间隔为1 Hz，每个子载波采用4-QAM调制，符号周期为1秒(OFDM IDFT/DFT 4-QAM FFT/IFFT)

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.)

The HART Application Guide has been created by the HART Communication Foundation (HCF) to provide users of HART products with the information necessary to obtain the full benefits of HART digital instrumentation. The HART communication protocol is an open standard owned by the more than 100 member companies in the HCF. Products that use the HART protocol to provide both analog 4–20 mA and digital signals provide flexibility not available with any other communication technology.

空间无线信道建模程序matlab，考虑了多径延迟，多普勒效应，信号的角度扩展（拉普拉斯分布），MIMO，可以产生MIMO信道矩阵。(Spatial channel modeling procedures matlab, taking into account multi-path delay, Doppler effect, the signal point of view the expansion of (Laplace distribution), MIMO, can generate MIMO channel matrix.)
