5 Threads found on edaboard.com: Pskdemod
Hello Friends. I want to explore matlab in digital communication step by step. I need help in developing basic code for bit error rate and Data rate.Please help me find this. For example i used "pskmod" inbuilt function and passed the modulated data through a awgn noise after that i demodulated using "pskdemod" inbuilt function now i want to calcu

is 't' your trellis? and what 'tb' are you using? and since you're essentially doing a bpsk demod with pskdemod(b2,2), try doing a slice to implement hard decision bpsk demod (demodout = (b2>0) ), or use b3 = real(b3) in your code.. post the answers you find, and we'll discuss further.

use pskdemod(Input,4)
I assume you coded wav data into binary before transmitting it.
To get help you have to explain your question is more detail

Hello,
I am trying to plot the BER of BPSK, but it does not work correctly, I do not know why. I am using the following code:
M=2;
chan=rayleighchan(1/10000,100);
tx=randint(50000,1,M);
txSig=pskmod(tx,M);
y=filter(chan,txSig);
SNR=0:2:20;
for n=1:length(SNR)
rxSig=awgn(y,SNR(n));
rx=pskdemod(rxSig,M);
[nErrors,BE

Hello everybody !
I want to simmulate a Rayleigh channel with BPSK signal with following code
===============================
chan=rayleighchan(1/10000,100);
M=2;
tx=randint(nbit,1,M);
dpsksig=pskmod(tx,M);
fadedsig=filter(chan,dpsksig);
snr=0:1:20;
for n=1:length(snr)
rxsig=awgn(fadedsig,snr(n));
rx=pskdemod(rxsig,M);
