FFT_for_lottery
- 自己写的matlab程序，用FFT分析3年来双色球彩票走势，当然了，还没有成功：），努力中。。。 有兴趣者可以共同探讨。-himself wrote the Matlab procedures, using FFT analysis of three years Shuangseqiu Lottery trend, of course, also without success :) efforts. . . Interested parties can jointly explore.
OFDMsystemsimulationfullversion
- This simulation scr ipt set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes

SARReturnWaveSignal
- 基于FFT的快速SAR分布目标回波模拟算法. 大面积分布目标的合成孔径雷达(SAR)回波模拟需要大量的运算，文中提出了一种合成孔径雷达回波模拟的快速算法，算法利用时域插值和FFTl’来缩减运算量，对于大面积目标回波模拟时，该算法有很高的效率。文中详细分析sinc函数插值所带来的误差以及补偿方法，并在次基础上提出了一种利用增采样插值方法，该方法以增加少量运算为代价，使得模拟精度的大幅度提高。文中比较了传统方法和基于FFTl’的快速SAR分布目标回波模拟算法的模拟结果，证明了这种快速算法确实
