I think that problem occurred at SNR or BER.

I need matlab code to obtain BER vs SNR curve for binary on-off keying. have a peek at this web-site
Reply Krishna Sankar December 7, 2009 at 5:33 am @fatima: I believe it should be reasonably straightforward to modify the gaussian channel used in this post to a binary symmetric channel. good luck.

The information BER, approximately equal to the decoding error probability, is the number of decoded bits that remain incorrect after the error correction, divided by the total number of decoded bits I have something personal to email to you with respect to my undergraduate project work.Thanks. Thanks very much. I was stuck with re creating the 1st fig in the paper.
A more general way of measuring the number of bit errors is the Levenshtein distance. However, in my design, there are two integrators. I corrected it. Analysis of the BER The BER may be evaluated using stochastic (Monte Carlo) computer simulations.
for example: if I transmit bit : 1; 0; 1 , I received : -10.8; +9.7; -11.2.
