Satisfactory solution of this problem may require that the students
consider the relationship between the Fourier series and the
Fourier transform, and to consider deeply what Eric said
above ;-).

What would substitute for the CP if it's not there? Dead time or
just eliminate the CP and butt the symbols up against each other?
It'll make a difference...

Why is the difference? Cyclic prefix is just the copying a portion of
the symbol. Any
pointers might be helpful.

Dear all,
I want to know what is the difference of power spectrum of OFDM with
no added cyclic prefix and power spectrum of OFDM with added cyclic
prefix. Please help me to overcome this problem.
Thanks in advance.
Best regards,
