I 'm working on a DVB -T chain .the BER decreases as SNR inceases until a specific value of SNR(17-18db) onwards this limit the BER increases as SNR increases.
Anyone can explain this please??
Hi,
I m working with cocentric studio system and i simulate with matlab.In fact i have increased the number of simulated bits(from 1e7 to 1e8) to see this result!
sorry what do you mean by a non stable system?
- With SNR between 17 and 18 dB and the DVB-T communication system contain a convolutionnal code and Reed solomon code to correct errors, you are supposed to get no error with only 1e7 to 1e8 transmitted bits.
- non stable system, that is mean not correct. Try to simulate without noise and check if your system decode with 0 error.
