Hi All I am simulating OFDM in MATLAB.. i have completed most of the part.. I have one doubt..i get complex signal to be transmitted that is real and imaginary... how do i pass such a signal through channel filter.. so as to simulate actual scenario of real world channel propagation.... should i pass the real part only Please help me on this sandeep

Either you need to have carrier modulation after your OFDM modulator, or you need to constrain the input signals to have conjugate symmetry to get a real-valued output from your OFDM modulator.
