Beam propagation method - light propagation along planar waveguide, which is broken. The code could be easily modified for unbroken waveguide and two waveguides.(Beam propagation method- light propagation along planar waveguide, which is broken. The code could be easily modified for unbroken waveguide and two waveguides.)

说明：  有一些matlab的相关程序，也有M文件(linear least squares estimate)

说明：  该代码主要实现的功能是空时编码误码率，误码率随着信道的变化而变化(THE BER OF THE SPACE BASE CODE，the ber varied with the channel)
