归一化功率谱密度 signal

基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置(RSSI-based positioning, known to launch the node transmission signal strength, the receiving node according to received signal strength, transmission loss calculated using the theory or experience loss of signal propagation model will spread into the distance and then calculate the location of the node)

模拟退火算法，模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。(Simulated annealing algorithm, simulated annealing algorithm derived from the principle of solid annealing, heating the solid to the full high, let it slowly cooling, heating, the solid particles with the internal temperature rise to disorder symptoms, which can be increased, and slowly gradually cooling particles in an orderly manner, at each temperature to reach equilibrium, and finally at room temperature reaches the ground state, which can be reduced to a minimum.)
