MC20基站定位代码

布谷鸟搜索算法的总结，每一个鸟巢位置对应着一组BP神经网络初始连接权值和阀值，BP网络根据连接权值和阀值对训练集进行训练，计算每个鸟巢位置对应的预测精度，并根据预测精度找到当前最优鸟巢

仿VS编辑界面，采用反射机制

调频接收机是用来接收广播节目的收音机，这种收音机是用鉴频器对调频的高频信号进行解调的。调频信号本来是等幅的。但在传输的过程中，由于各种干扰，使幅度产生起伏。为了消除干扰的影响，在鉴频之前，常用限幅器进行限幅，使调频信号恢复成等幅状态。根据超外差式调频收音机的原理，我们可以将整机电路分成以下几个模块：输入调谐回路、高频放大电路、混频电路、本机振荡电路、中频放大电路、鉴频器电路、低频功放电路。
