（1）请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。
（2）在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与(1)的曲线进行对比。
((1) derived from single-Path Rayleigh channel coherent demodulation of BPSK theoretical bit error rate performance and draw-bit signal to noise ratio and bit error rate curve. (2) in a single Path Rayleigh channel, please design a guided night-assisted channel estimation methods, using Simulink simulation, surveying BPSK BER performance, drawn-bit signal to noise ratio and bit error rate curve, and with (1) comparing the curve.)

Localization-based-on-LS-SVR-in-WSN
文章针对无线传感器网络(WSN)节点定位算法DV-Hop的节点间距离沽计误差对定位准确度影响较大的问题，提出一种基于LS-SVR(最小二乘支持向量回归机)的定位算法L-LSSVR.
(Aiming at solving the problem of the significant influence of distance estimation error onlocation accuracy of DV-Hop in Wireless Sensor Networks (WSN), a new node localizationmethod based on LS-SVR (L-LSSVR) is proposed.)
