hi
i didnt undrestand your questions , but if you are looking for amethod to determine the maximum data rate possible on a channel , then there is agood paper by Blahaut that he develops one of the only two algrithemes that can measure the channenl bandwidth and data rate( practical values) ...
If I am using BPSK with coding rate of 1/2, and I am looking for the SNR values. So, what should I assume with the bandwidth in C=BW*log2(1+S/N). I read some of the text book saying that, shannon limit for such coding rate and BPSK is 0.188 dB. How should I apply it? Is it 0.5=BW*log2(1+s/N)?
what is 0.188 dB? SNR or energy per bit(Eb/N0)?? What the text book do you read? The shannon limit is -1.6 dB (Eb/N0) regardless modulation schemes. Also the rate 1/2 is a rate for BSC channel whose the maxmimum capacity is one. This is in the different part of the system.
