基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

pitch 的相关程序，自己编写的，可以条用，很好的，赶快下吧(pitch of the relevant procedures, their preparation, can be used, very good, quickly, are you)

CML for LDPC coding using DVBSc

generation of pctc in matlab...simulation code

本程序用以仿真块状导频时不同信噪比条件下的误码率和均方误差，信道估计采用最小二乘法和改进的最小二乘法。 (The pilot program for the simulation block different SNR when the bit error rate and mean square error channel estimation using the least square method and the improved least square method.)
