Abstract: In OFDM systems, cyclic prefix (CP) insertion and removal enables the use of a set of computationally efficient single-tap equalizers at the receiver. Due to the extra transmission time and energy, the CP causes a loss in both spectrum efficiency and power efficiency. The last few samples of OFDM symbol are extracted and prefixed at the beginning of the transmission. This part is known as cyclic prefix and the time interval comprising of these repeated samples is known as "guard interval (Tg)".

Cyclic prefix removal

A pulse shaping filter for the OFDM systems is proposed to remove the constraint of CP. Also, transmit and receive filters in OFDM system suffer from poor frequency response because of the use of rectangular window function.

The one way to do this is by copying or duplicating an initial part of the symbol, and inserting the end of it. And it acts as Cyclic Prefix. In conventional OFDM modulation technique uses cyclic prefix (guard band) for prevention of interference in carrier signal. 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.
