QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

matlab，仿真设计，再设计的基础上进行了一定的开发，使得编译连接有了较好的改善(Build connections )

matlab的又一本教程，内用详细，丰富。分类明确，是一本很好的工具书。(matlab another in this tutorial, which used detailed, rich. Categories clear, is a very good tool.)

首先将测量值与估计值都进行模糊化，然后计算测量值与估计值之间的格贴近度, 利用贴近度来描述各个传感器在测量中的权重，最后得到融合结果。(First, the measured values and estimated values are fuzzified, and then calculated between measured and estimated values of the lattice close to the degree of closeness to describe the use of various sensors in the measurement of weight, and finally get fusion.)

令信号长度为N=256，试分别用BT法和周期法估计产u（n）功率谱(So that the signal of length N = 256, respectively, the estimated production test u (n) the power spectrum with BT and Cycle Methods)

Local vote decision fusion is a recently proposed method of target detection for a wireless sensor network in which individual sensors combine their decisions with those of their neighbors and report to a fusion center only if there is a majority in favor of presence. The fusion center reaches afinal decision about presence or absence according to whether the number of positive reports exceeds a threshold. This has been shown to give a higher target detection rate, for a specified false al
