电力线信道噪声模型matlab仿真，在输入端把脉冲噪声模型放入电力线OFDM通信系统，输出端用特定算法解码。(The algorithm estimates the impulsive noise in powerline communication, and subtract out an estimate of the impulsive noise in the current OFDM frame.)

GSM信道估计，c实现，包含详细的报告说明，很全。(GSM channel estimation, c achieve, contains a detailed description of the report, it is.)

说明：  本程序仿真了电子扫描阵列天线方向图，实现了不同参数情况下栅瓣现象、主瓣宽度和功率增益随扫描角变化情况(This program simulates the electronic scanning array antenna pattern, and realizes the change of grating lobe phenomenon, main lobe width and power gain with scanning angle under different parameters.)

预留子载波法(TR)降低PAPR的matlab算法(Reserved subcarriers method (TR) matlab algorithm to reduce the PAPR)

用VC++6.0编写的USB通讯测试的程序，可以实现查找PC的USB外设，读取USB外设的设备描述符等功能。对USB通讯初学者有很大的帮助。(Written in VC++6.0 using USB communications test procedure, can be achieved to find PC' s USB peripherals, read the USB peripheral device descriptor functions. USB communication to the very helpful for beginners. )

OFDM系统在QPSK与16QAM调制下，误码率比较程序，希望对大家有一定用处(OFDM system with 16QAM QPSK modulation, error rate procedures, We hope to have some use)

说明：  matlab锁相环解决相干光通信系统激光器相位噪声(Phase-locked loop to solve the phase noise of laser in optical communication system)

说明：  用hspice写了一个做了16bit kogge stone四层点操作的树形加法器静态逻辑网表，所有管子的尺寸按照0.25u的尺寸设计挂上测试文件跑以后逻辑没问题，但是按照拉贝尔那本书上讲的关于逻辑努力优化的方法优化，在输入级加了两级buffer，只对最长路径支路尺寸优化(Use HSPICE to write a 16bit kogge made stone four layer tree adder static logic netlist, all pipe sizes according to the size of design 0.25u hang test file to run after the logic is no problem, but in accordance with the method of logic optimization efforts of Labelle's book about the optimization, plus two buffer in the input stage, only the longest path branch size optimization)
