Matlab入门级OFDM仿真，包括每个步骤的波形，星座图，频谱等 含循环前后缀，时域加窗等，适合刚接触OFDM的学习 (Matlab entry-level OFDM simulation, including each step of the waveform, constellation diagram, spectrum including cycles before the suffix, such as time-domain windowing for OFDM new to the learning)

OFDM中降低峰均比的方法，将传统的SLM法，改进的SLM法和限幅加改进SLM法进行比较(Compare OFDM PAPR reducing methods in the traditional SLM method, improved SLM method and limiter plus improved SLM method)

蓝牙模块 VisualStudio2008 蓝牙通讯(bluetooth VisualStudio2008 bluetooth)

根据蒙特卡罗仿真原理，对8DPSK进行特卡罗仿真，对误码率进行分析()

说明：  TDMA的opnet仿真模型，比较简单，适合初学者(TDMA the OPNET simulation model is relatively simple, suitable for beginners)

modbus rtu 校验vb源码，对VB学习者很有帮助(modbus rtu checksum vb source code, useful for VB learner)

关于超宽带多用户检测的大家可看看，很好的程序(on Ultra-Wideband Multi-User Detection you can see, very good procedures)

ofdm信道估计仿真（ls算法，mmse算法，还有一种改进的mmse算法lmmse，可以直接在马特拉并上运行）(OFDM channel estimation simulation (ls algorithm, mmse algorithm, as well as an improved MMSE algorithm lmmse, can be directly in the Matra and run))

Digital Communication Solutions Vol 4

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)
