matlab实现 STBC-MIMO-OFDM

用于变电所的电力103通信测试的源代码,主要用在工控行业(103 for electricity substation communications test source code, mainly used in the industrial sector)

说明：  基于matlab实现OFDM，调制方式为QPSK，可以对信道的状态进行估计(OFDM is realized based on MATLAB, the modulation mode is QPSK, and the channel state can be estimated)

M-PSk(M=2,4,8)-grayencoded, in AWGN channel,plot BER and SER, compare it with theorical results

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.)

数字通信中的DBPSK调制解调的原理和过程, 通过用Matlab 对这一过程的编程,分析信号在理想信道和加噪信道中传输时的(The principle and process of DBPSK modulation and demodulation in digital communication are analyzed. By programming this process with Matlab, the transmission of signal in ideal channel and noised channel is analyzed.)

信道基本特性的仿真程序，包括小尺度衰落信道（频率选择性信道和时间选择性信道）的仿真，分集接收及误码率的仿真。(Channel basic characteristics of the simulation program. including small-scale fading channel (frequency selective channel and time-selective channel) simulation, Diversity reception and BER simulation.)

宽带OFDM信号模型的建立，用于宽带OFDM信号的DOA估计，已经用于毕业设计(Wideband OFDM signal model, for broadband OFDM signal DOA estimation, has been used for graduation)
