Hello everyone,
m = 2;
PU = 4;
NumBits=1000;
lamda_val=0.5;
si=rand(m,NumBits);
hi=rand(m,NumBits);
ni=rand(m,NumBits);
PU = input('Enter No. of primary user = ');
Fc = zeros(1, PU);
if PU >=1
for x = 1:PU
Fc(x) = input('Enter 1 for signal present and 0 for noise in channel = ');
end
else
disp('No primary signal detected');
return;
end
table = zeros(m,PU*NumBits);
for index = 1:(PU)
if Fc(index) == 1
for ii=1:m
temp(ii,:)=abs((hi(ii,:).*si(ii,:))+ni(ii,:)).^2;
end
else
for ii=1:m
temp_noise(ii,:)=abs(ni(ii,:)).^2;
end
end
table = [temp(ii,:) temp_noise(ii,:)]
end
can somebody tell me how to do this. I have to store values in rows.
I have edited the code for better understanding. Hope it helps.
If PU is 4 with values 1011, then values generated due to these values should be stored in concatenation to evaluate further.

This code is weird.
In each iteration of "index" you fill either a matrix temp or a matrix temp_noise with m rows of values.
Then you concatenate only the last (= ii-th) row of both of these matrices into a single row, and store this in the variable table. One the of these last rows was just created, and for the other one you use the one created one or more iterations ago.
At every subsequention iteration, this variable table is overwritten.
So, first you need to carefully think about what you are trying to do ....

I agree, I was trying to reverse engineer the problem from the code, but a clear example would help
