对BPSK进行了仿真，包括模块仿真和程序源代码仿真，我这边可以运行(For BPSK by simulation, including the module source code simulation and simulation)

说明：  这是从IGS上下的精密卫星钟差信息 间隔为30秒的钟差信息 希望对相关人员有所帮助(This is down from the IGS precise satellite clock difference information 30 seconds interval clock difference information related personnel would like to help)

LDPC Codes – a brief Tutorial Bernhard M.J. Leiner, Stud.ID.: 53418L bleiner@gmail.com April 8, 2005

说明：  该资源为应用GNUradio工具，对USRP的开发，主要实现了频谱感知，以及根据频谱感知的结果进行ofdm通信的功能(This resource is the development of USRP using gnuradio tool. It mainly realizes the function of spectrum sensing and OFDM communication according to the result of spectrum sensing)

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

实现Polar码编码译码，SC译码，简单实用，运行速度快(Polar MATLAB include encode and decode useful and simple)

说明：  主要介绍了8255接口的基础知识及其实例的应用，并借助几个小例子，介绍如何设计和使用8255(It mainly describes 8255 which is a paralel port)

此代码通过随机生成二进制码，对其进行二进制差分调制，以及加入高斯白噪声后对其解调计算误码率，绘制出其输入信噪比与输出信噪比的实验曲线及理论曲线的比较。(This code generates binary codes randomly, modulates them by binary differential modulation, demodulates them with Gauss white noise and calculates the bit error rate, draws the experimental curve and theoretical curve of their input signal-to-noise ratio and output signal-to-noise ratio.)

说明：  很久很久之前，收藏的一份 清华大学 p2p相关的研究文献，希望对有需要的人有帮助，非常难得(Long, long ago, a collection of P2P-related research literature collected by Tsinghua University, hoping to help people in need, is very rare.)
