Hi,
According DVB-T demo in Matlab Communication block set, it is a fair simulation model with not having guard interval and so on. But we can simulate in AWGN noise and this shows zero BER. But after i modified by inlcuding Rayleigh Multipath channel the BER is increasing to 0.5. That means i need to add something at the reciver end to minimize the BER. And i hope that would be Equalizer as per my Digital communication Knowledge. Pardon m guys, I'm poor in Digital Electronic as my core subjects are programming and no way related to communications but My masters level in sweden included this topic and i don't know why!!(.. But i learned few interesting topics like Mathlab coding and Simulation of various communication standards myself and that pushed me to take thesis on DVB-T systems as i'm big fan of Video broadcasting systems. My knowledge in Equlaizers is zero and i want learn something big. But i dont find a single releavant material. Coming to the point, when i added the Rayleigh Multipath Fading block along with AWGN block to channel the BER went down to 0.5 and i need to minimize that by adding equalizer. So, which equalizer is suitable for 2k broadcasting when used 64QAM on OFDM to minimize the multipath fading? Explanation is OK and if there is an example model it would so great..Guys, please don't make my post dumb and i'm dying to find the answer here. Please share your knowledge and enligten me..otherwise it would be choatic for me and i might end up doing nothing by the end of this semester..Atleast a small clue would be so grateful..I hope a reponse from Geeks in this forum..thanks all in advance..
