I want to give an input signal as QPSK ...Let it be S
And take the idft for the same..let it be X
S varies from S(0) to S(Nt-1)
X varies from X(0) to X(Nt-1)
This is MIMO ofdm project..how can i implement this?
Nt=2 (number of transmit antennas)
My project goes like this:
Give QPSK(S0,S1) as input signal; Take IDFT of QPSK to get X0,X1=X;
Add CP(cyclic Prefix) = 15;
We will get channel response h0,h1=H (Note: I have got channel response)
Then Remove CP and take DFT to get Received signal=HX
Pass it to FEQ to get S0^ and S1^
I wanted to know how should I give QPSK and take IDFT for the same
