关于蓝牙编程技术，有这方面需要的，提供给大家参考(Programming on the Bluetooth technology to provide for your reference)

无线定位技术仿真模拟，加有高斯白噪声干扰，能精确到1米之内。(Wireless location technology simulation, plus Gauss white noise interference, can be accurate to 1 meters.)

说明：  GPS信号模拟软件，模拟GPS设备向串口输出0183格式标准语句，配合串口虚拟工具使用，可以在普通电脑上调试(GPS signal simulation software, which simulates GPS equipment to output 0183 standard statements to serial port, can be debugged on ordinary computer with serial virtual tools.)

说明：  该MATLAB用以计算LTE下行业务数据在高斯信道下QPSK的误码率(The MATLAB is used to calculate the error rate of QPSK of LTE downlink data in Gaussian channel)

LTE ADVANCED ,LTE PHY Downlink with Spatial Multiplexing

仿真MIMO系统，采用STBC编码，发射天线数目为2，接收天线数目为2(The MIMO system is simulated with STBC coding, the number of transmit antennas is 2, and the number of receiving antennas is 2)

DRM(Digital Radio Mondiale)系统采用OFDM调制方式， 引入了先进的信源信道编码和调制技术，使得AM波段的音频广播质量大大提高，在保持现有10kHz带宽时接近了FM广播的质量[5](DRM (Digital Radio Mondiale) system uses OFDM modulation, the introduction of advanced source-channel coding and modulation techniques, making AM-band audio broadcast quality greatly improved, while maintaining the existing 10kHz bandwidth close to the quality of FM broadcasting [5])

数据通信,没什么很详细的,只是一个素材源玛(Data communication, not very detailed, just a material source ma)

说明：  利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)

降低PAPR编码方法中的格雷码仿真程序，能仿真出结果。仿真参数为:子载波数目N=16,BPSK调制，过采样因子w=16，(Reduce the PAPR coding method of Gray code emulator, simulation results. The simulation parameters: number of subcarriers N = 16, BPSK modulation over-sampling factor w = 16,)
