MIMO OFDM
实现基于STBC的MIMO_OFDM通信系统在不同信噪比情况下接收端的误比特率的仿真。发射端包括基于基带调制、空时编码、导频插入、IFFT、串并合并以及添加循环前缀;接收端包括去除循环前缀、取出导频估计信道、FFT运算以及并串合并,空时解码等。仿真中采用QPSK、空时编码采用4*3的复正交空时编码矩阵。OFDM子载波数为100,每个子载波传输66个符号,每个符号2比特。IFFT长度为512个符号。发射天线为3个接收天线为2个。(The BER simulation of MIMO_OFDM communication system based on STBC under different SNR is realized. The transmitter includes baseband modulation, space-time coding, pilot insertion, IFFT, serial-parallel combination and adding cyclic prefix; the receiver includes removing cyclic prefix, extracting pilot estimation channel, FFT operation, parallel-serial combination, space-time decoding, etc. The complex orthogonal space-time coding matrix is used in QPSK and space time coding in 4*3. The number of OFDM subcarriers is 100, and each subcarrier transfers 66 symbols with 2 bits per symbol. IFFT is 512 symbols in length. The transmitting antenna is 3 receiving antennas, 2.)

putty_V0.63.0.0.43510830
PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台,在最近的版本中开始支持各类Unix平台,并打算移植至Mac OS X上。除了官方版本外,有许多第三方的团体或个人将PuTTY移植到其他平台上,像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件,主要由Simon Tatham维护,使用MIT licence授权。随着Linux在服务器端应用的普及,Linux系统管理越来越依赖于远程。在各种远程登录工具中,Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端,但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为 0.68 latest release(PuTTY is a Telnet, SSH, rlogin, pure TCP, and serial interface connection software. The earlier version supported only the Windows platform, and in recent versions began to support various Unix platforms and was intended to be ported to Mac OS X. In addition to the official version, there are many third party groups or individuals that migrate PuTTY to other platforms, such as Symbian based mobile phones. PuTTY is an open source software that is maintained primarily by Simon Tatham and licensed using the MIT licence. With the popularity of Linux applications on the server side, Linux system management is becoming more and more dependent on remote. Putty is an excellent tool for various remote login tools. Putty is a free, Telnet, SSH, Telnet, and rlogin client on the Windows X86 platform, but it is no less functional than the business class tools. The latest version is 0.68 latest release)

bpsk_Awagn_Rayleigh
说明: 实现了一个直接扩频系统,使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下,误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m
Steps for simulation:
1] Run jakesmodel.m first
2] Then run bpsk_spread.m .
3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented
4] The resulting performance is stored in BER_awgn.
5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file.
6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable.
7] Run the simulation.
To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray
