Hello,
Some variables in some parts of the codes (Chapter 10 and Chapter 11) are not defined.
For example, the branch_metric in STTC_detector.m and y and H as the inputs to the functions in Chapter 11.
Could you please help with solving the issues?
Thanks
Matrix dimensions must agree.
Error in OFDM_basic (line 85)
Neb=Neb+sum(sum(de2bi(X_r,Nbps)~=de2bi(X,Nbps)));
I managed to find a workaround, you can find the corrected (working) file at this address:
[https://gist.github.com/andi-ra/34054a494054d6714f2a374f5738951f]
Everything seems working, feel free to reach if my solution is not correct. Thank you for that great book!!
function [modulated_symbols,Mod] = mapper(b,N)
% If N is given, it generates a block of N random 2^b-PSK/QAM modulated symbols.
% Otherwise, it generates a block of 2^b-PSK/QAM modulated symbols for [0:2^b-1].
