区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier transform to estimate the class LPF signal. It has higher learning value)

用C语言编写的LDPC译码程序，希望对大家有用(Using C language LDPC decoding process, in the hope that useful)

PCI slave IP core, in VHDL language ,has been verified,it is very easy to use. it is an ideal IP to study PCI,design PCI Bridge

QPSK的编译 设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(QPSK compiled Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK variety of modulation and demodulation mode corresponding to the main (sub-coherent and non-coherent) error rate statistics, and with the theoretical value comparison, a graphical representation of bit error rate and SNR relationships.)
