用Excel计算灰色预测模型，每个步骤都有，十分详细。(Calculating Grey Prediction Model with Excel)

最小二乘法(LS)仿真6个参考节点定位一个定位节点，利用RSSI与距离转化的公式求解距离。(Least squares (LS) simulation 6 reference node positioning a positioning node, the use of RSSI and distance into the distance formula to solve.)

粒子群算法，也称粒子群优化算法或鸟群觅食算法（Particle Swarm Optimization），缩写为 PSO。它具有精度高，收敛快等优点，广泛用于系统辨识、函数优化等领域。文件pso.m是粒子群算法辨识程序，在此基础上，需要自行编写目标函数计算程序以实现不同系统的参数辨识。(Particle swarm optimization (PSO), also known as particle swarm optimization algorithm or bird swarm foraging algorithm (Particle Swarm Optimization), abbreviated as PSO. It has the advantages of high precision and fast convergence. It is widely used in system identification, function optimization and other fields. The document pso.m is a particle swarm algorithm identification program. On this basis, it is necessary to write an object function calculation program to realize the parameter identification of different systems.)
