The receiver is typically configured to discard the  However recently I was told to add variable offset to start of cp removal but how this is computed or how does it relate to multipath I got no idea. I  [1]In this article the influence of cyclic prefix and pilot insertion technique on an OFDM On receiver side CP is first removed and then FFT of that data matrix is  cyclic prefix, null tones, and OFDM channel estimation/correction. However, this lab current removal should not affect the index for the next removal. Use a for  At the receiver side, a reverse process is performed. The serial data is received and converted to the parallel form. Then the CP is removed. After removal of CP,   Implementation of OFDM Modulator and Demodulator with Cyclic Prefix : Demodulator.

However, this lab current removal should not affect the index for the next removal.

From that process waste some valuable bandwidth using cyclic prefix. Now in these day wavelet transform function replace FFT process for removal of cyclic prefix and improve the efficiency of bandwidth.

After removal of cyclic prefix, Fast Fourier Transform is performed. Then the signals are demodulated using different modulation schemes to get the original binary data [13]. Fig. 1Block diagram of OFDM system . Fig.2 shows the proposed OFDM system model.

I try to simulate OFDM design, i use FFT v.5, with cyclic prefix insertion, but i don't know how to remove that cyclic prefix before prosessed to the FFT (in receiver). i also confuse about port cpv and rfs, how too use the port? thanks in advanced, suyoto
