newmsg = decode(codenoisy,n,k,'hamming'); % Compute and display symbol error rates. In either the bit- or symbol-counting case, the error rate is the number of errors divided by the total number (of bits or symbols) transmitted.Note: To ensure an accurate error rate, Supported modulation types are listed on the reference page for semianalytic. Bit Error Rate For Qpsk Matlab Code num = ones(Nsamp,1)/Nsamp; den = 1; EbNo = 0:20; % Range of Eb/No values under study ber = semianalytic(txsig,rxsig,'qam',M,Nsamp,num,den,EbNo); % For comparison, calculate theoretical BER.
