说明：  瑞利衰落信道中空时编码仿真程序： 1.2根发射天线、1根接收天线2.最高信噪比为12dB，即仿真范围为0dB到12dB3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真4.每一帧数据为24个QPSK符号(Rayleigh Fading Channels Space-Time Coding Simulation Program: 1.2 transmission antennas, a receiving antenna 2. The highest SNR 12dB, that is, simulation range of 0dB to 12dB3. In each signal to noise ratio conditions, the number of symbol error over 20 that is, to stop the signal to noise ratio under the conditions of simulation 4. each frame 24 QPSK data symbols)

变压器局部放电的定位，运用music算法，可实现变压器中单点、两点或三点的定位(Positioning transformer partial discharge, the use of music algorithm can achieve a single point of the transformer, two or three point positioning)

对线性均衡、判决反馈均衡和最大似然序列估计均衡等三种方法的实现和误码率的分析。(Of linear balanced, decision feedback equalizer and maximum likelihood sequence estimation of three methods such as balanced realization and BER analysis.)

The function implements an horizontal magnetic dipole (along the x-axis) and calculates the x and z component of the magnetic field for y=0. The script allows to set a wanted value of multiple layers, with their own relative electric permittivity, relative magnetic permeability, conductivity (see the LAYERS PARAMETERS section in the script). The script finally produces an animation of the radiated field.
