hi ..
im doing my project in bpsk transceiver system using matlab coding... i am able to get coding for modulation .... but unable for demodulation... so any one help regarding that...
thanks in advance...
 

You would try multiplying by the same carrier used at modulation ,low pass filtering the output then using a decision device; if output>0 then 1 is detected else 0 is detected .
 
use co-herent carrier(at demodulation). what have u used for decision making device? r u using simulink? or just matlab m file(script file)?
 
thanks for ur reply yar...
if any one of u have a better program can u please mail that to me....
it will become easy for me to understand.....
thank u ...
 

This is my BPSK code... But remove the SNR part... Its very confusing and seems there is a minor mistake as far as adding noise is concerned...

Use noofbits as 10000 and not as i have used...
