`The statement in the subject is refering to Erich Cosby's tutorial for`

OFDM.

I'm simulating OFDM in Simulink with the aim of later converting it

for a DSP.

I use BPSK before the OFDM operation. With BPSK, all my binary inputs

would be converted to either 1 or -1 in the IQ spectrum. In Simulink,

the outputs contain very small values for the imaginary part i in the

range of around -16

eg, binary 1 would be 1+1.22e-16i and binary 0 would be otherwise..

Would this small imag value be sufficient to fulfill the statement and

produce a real time signal? Would it cause any problems with the DSP

implementation?
