encoding binary data using non return to zero

说明：  本文介绍了如何使用264芯片，并对可编程增益可调的滤波器max264做了具体说明.(for how to use max264)

这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性： 1. qpsk/16qam/64qam映射、解映射 2. OFDM调制解调（循环前缀，FFT等） 3. 非整数采样时刻多径时延的多径信道 4. Rayleigh或者Rician多径信道 5. 信道的连续时变（非block fading） 6. 线性插值信道估计 7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)

最近在做毕设，ldpc码的编解码实现，这个是verilog实现。(Recently completed the set up to do, ldpc code codec implementation, this is the Verilog implementation.)

这是一个在MATLAB环境下，UWB源码，很有参考价值(This is a MATLAB environment, UWB source, useful reference)

实用性代码，可以在手机等移动设备上很好的使用，可操作性强。(Usefulness of the code can be very good for use on mobile phones and other mobile devices operable.)
