Hi friends,
   
 I have been investigating on the applicability of power line communications techniques. I want
to simulate the plc system in  MATLAB (m file).The simulation includes FSK and PSK and OFDM
modulation and demodulation , error control coding , powerline channel and the noise over it.
 I have some problems with these simulations .
 I want to know if you have any MATLAB files (m files) about powerline background and impulsive
noise.
 
 thanks
