analyisis of BER vs SNR for BPSK

i want to plot the performance of BER vs SNR for BPSK........could anyone over here help me to write the codes for it .......thank you in advance !comment beside the function are appreciable.....and it would be better if you pls explain what are u going to do!

hi......i want to generate a binary signal and add a AWGN channel to it for a specific SNR ....actually i want to calculate the BER performance of the bpsk ....can anyone pls provide me the code of generating noise for specific SNR????and actually can anyone help me describing the procedure how to modulate and demodulate the BPSK for calculating BER vs SNR....thanks in advance!

there's a script in the file exchange http://www.mathworks.com/matlabcentral/fileexchange/25922-ber-of-bpsk-in-awgn-channel/content/bpskAWGN.m

and if you just need to plot the BER, use ber = berawgn(...)

I need the matlab code for plotting BER vs SNR in a AWGN channel using random code of length 31 for single user detection and multi user detection.please reply me asap
