Simulink (Rayleigh Fading) Help Required

Started by Ahsan Ali June 22, 2007
Hello Everyone!

I am Ahsan and i am doing my final year (UG) project on OFDM. I was supposed to simulate the effects of noise and multipath fading on OFDM signal. I am using SIMULINK as the simulation tool.I have completed the noise simulation using the AWGN channel in SIMULINK but when i insert the Multi-path Rayleigh Fading Channel in my model i get the following error:

Error reported by S-function 'scomtrigbuff2' in 'sound_testing/Multipath Rayleigh Fading Channel/Multipath Fading Channel/Fading Profile/Rebuffer with Input Trigger/S-Function':
The minimum input width must an integer scalar > 0

Kindly help me out as i am in the final stages of my project and i am unable to remove this error. Is there any other way that can help me to simulate multipath fading in SIMULINK?

Kind Regards
