无线传感器网络节点定位算法研究，APIT定位算法的源代码(Wireless sensor network node localization algorithms, APIT localization algorithm source code)

说明：  这个是多带谱语音检测，多带谱不仅具有谱熵的有点，还具有能量分析的有点，所以检测的效果很好！(This is a multi-band spectra of voice activity detection, multi-spectral bands not only has a bit of entropy, also has a bit of energy analysis, so the effect of a very good test!)

分析了该信号的时域、频域、倒谱，循环谱等,有较好的参考价值，考虑雨衰 阴影 和多径影响。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. There are good reference value, Consider shadow rain attenuation and multipath effect.)

说明：  提供了三个经典遗传算法的案例，内有源代码。欢迎大家交流，共同进步。(Three cases of classical genetic algorithm are provided with code. Welcome to communicate and make progress together.)

粒子群优化支持向量机对电池寿命进行预测，利用粒子群优化支持向量机参数(Particle swarm optimization support vector machine is used to predict battery life, and particle swarm optimization is used to support SVM parameters)
