How can I generate orthogonal spreading sequences in Matalb in frequency and time domain? What properties a set of spreading sequences should have ?
e.g in time domain
x=randi([0 1], 10,1); % time domain signal
SprdSeq= rand(20,20); %% HOW to GENERATE ORTHOGONAL ?
Spreadedsignal= SprdSeq *diag(x);
In frequency domain should I take fft of both Sprding seq and the signal and then convolve ??
e.g in time domain
x=randi([0 1], 10,1); % time domain signal
SprdSeq= rand(20,20); %% HOW to GENERATE ORTHOGONAL ?
Spreadedsignal= SprdSeq *diag(x);
