杰理得蓝牙通讯程序，可用于蓝牙和FM音箱的开发。(Bluetooth Communicator)

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.)

说明：  无源被动雷达利用距离-多普勒信息实现目标定位(Passive Radar Detection using Range-Doppler Transformations get target location)

LDPC最小和译码算法，c语言实现，适合初学者(Minimum and LDPC decoding algorithm, c language, suitable for beginners)

说明：  基带信号bpsk仿真，基带传输基本方波信号、sinc信号，对过程添加高斯白噪声，接收端用匹配滤波器进行接受，计算实际信号误码率，并于理论误码率进行比较(BPSK simulation of baseband signal. Baseband transmits basic square wave signal and sinc signal. Gaussian white noise is added to the process. Matched filter is used to receive the received signal. The error rate of actual signal is calculated and compared with the theoretical error rate)

分布式一致性协议，很适合刚接触一致性的新手(The consistency of distributed agreement, it is very suitable for new to novices)

本代码描述了OFDM/OQAM的基本仿真框架，AWGN信道下的ber性能。OFDM/OQAM 是一种很好的多载波系统。(This code describes the basic simulation framework for OFDM/OQAM ber performance in the AWGN channel. OFDM/OQAM is a good multi-carrier system.)

Matlab产生M-psk信号,用SVM实现对M-psk星座图的非线性决策边界,使用训练后的模型对测试数据进行预测(Realization of nonlinear decision boundary for M-psk constellation using SVM)

OSPA 距离计算 用于多目标检测使用的方法。 一键计算OSPA距离。使用前请仔细阅读readme 文件。严格按照步骤操作。(OSPA distance calculation. Perfect solution for OSPA calculation. Make sure you go through the read me file before using it.)
