qam matlab 仿真简介，自己看看就知道了。。。。(qam matlab )

基于循cp的粗小倍数频偏估计 利用ofdm符号的循环前缀(Cp-based crude through a small multiple frequency estimation using the ofdm cyclic prefix symbol)

详细的介绍了matlab和VC++混合编程时的方法过程，对于想实现混编的同志很有帮助，希望能帮得到大家。(A detailed description of the matlab mixed programming software and other methods when programming process, for those who want to achieve mixed comrades helpful, hoping to help get everyone.)

掌握用MATLAB求无穷级数的和、求幂级数 的收敛域、展开函数为幂级数以及展开周 期函数为傅里叶级数的方法(infinite series)

说明：  OFDM的SLM算法的实现和不同通道数下的比较(The SLM OFDM algorithm implementation and the comparison under different number of channels)

介绍了一种构建在定点DSP上的高速瑞利衰落信道仿真模型。通过应用确知性瑞利过程的理论，使得仅需要较少的低频正弦波分量以及简单的运算即可实现较高精度的信道建模；进而可采用查表法并结合TMS320C6202定点数字信号处理器的高并行性和处理能力构造高速的仿真模型(Construction of a fixed-point DSP in the high-speed Rayleigh fading channel simulation model. Through the application process unascertained Rayleigh theory, only need to make small low-frequency sine wave components and the simple operation can achieve higher accuracy Channel modeling; then use look-up table method and combination TMS320C6202 fixed-point digital signal processor parallel and can handle Construction of the high-speed simulation model)

运用粒子群优化算法对ARMA(p,q)模型的阶数进行优化是可行的，且利用优化后的ARMA模型对航空发电机状态趋势进行分析的结果十分准确，与原始数据所表现出的航空发电机状态变化趋势基本一致。经计算，此时分析结果的平均相对误差较小，仅为1.38 ，与优化前构建的ARMA模型相比，平均相对误差降低0.23个百分点，优化效果明显。(Using particle swarm optimization algorithm to optimize the order of the ARMA (p, q) model is feasible, and the use of the results of the ARMA model optimized air generator status trends analysis is very accurate, and the raw data showed aviation the generator status consistent trend. Calculated analysis of the results, the average relative error is small, only 1.38 , compared with the the ARMA model built before optimization, average relative error is reduced by 0.23 percentage points, to optimize the effect is obvious.)
