本资源为多重信号来波方向估计算法的MATLAB实验仿真，压缩有MUSIC,PM，四阶累积量等几种方法的DOA估计算法仿真。资源整理不易，请务必珍惜。(This resource is the MATLAB simulation of multiple signal direction of arrival estimation algorithm, compression MUSIC, PM, fourth-order cumulant and other methods of DOA estimation algorithm simulation. Resource consolidation is not easy. Please treasure it.)

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)
