基于OFDM系统，实现classen,Moose提出的频偏估计技术，(Frequency offset estimation technique proposed by Classen and Moose based on OFDM sys)

实现了QPSK的调制，使用了ise自带的dds的IP核(QPSK is modulated and the IP core of DDS is used in ise.)

极化码编译码在matlab下的仿真 误码性能分析(Analysis of Error Performance of Polarization Coding and Decoding under Matlab)

high performance communication networks presentation

the pdf entitled The Modulo Lattice Channel The Key Feature in Precoding is attached

基于互相关函数，采用求和广义互相关函数(summed-GCC)法用于机器人系统平台。由于采用不同的映射函数(mapping functions)，GCC法在该平台下，只需三个麦克风即可进行三维定位，突破了基于TDOA法进行三维声源定位最少需4个麦克风的限制(Based on cross-correlation function, using generalized cross-correlation function sum (summed-GCC) method for the robot system platform. Because of using different mapping function (mapping functions), GCC method in the platform, the only three to three-dimensional microphone positioning, a breakthrough TDOA method based on three-dimensional sound localization will take at least four microphone restrictions)
