matlab实现 STBC-MIMO-OFDM

说明：  this is official usb2.0 protocol

说明：  行商问题，自动生成最短路径。该算法可以生成经过拓扑每一点一次且仅一次最后回到起点的最短路径。(TSP problem: how to generate the minimal path for a salesman traveling among a set of points.)

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.)

AWGN信道的代码，实现简单易懂，用C写的(AWGN channel code is simple to understand, written in C)

调制信号的高阶累积量仿真，包括16qam，32qam，BPSK,QPSK,4ASK(Simulation of higher order cumulants of modulation signals, including 16QAM, 32qam, BPSK, QPSK, 4ASK)

说明：  数字滤波器的代码，可用于运行仿真IIR与FIR类滤波器。(The code of the digital filter can be used to run simulation IIR and FIR type filters.)

i c q 即 时 通 信 软 件， j a v a 实 现。 很 好 的 学 习 软 件。(icq instant messaging software, java implementation. Very good learning software.)

关于MIMO-OFDM的信号检测方法，ML检测(Signal detection method for MIMO-OFDM, ML detection)

利用matlab实现OFDM的接收和发送，QPSK调制，IFFT串并转换(Receive and transmit OFDM, QPSK modulation, IFFT series-to-parallel conversion using MATLAB)
