An important role performed by Zero Padding (ZP) in Multi-Band OFDM (MB-OFDM) System. This role show for low-complexity in résistance against multipath interference by reducing Inter-Carrier Interference (ICI) and eliminating the Inter-Symbol Interference (ISI) also, zero-padded suffix can be used to eliminate ripples in the power spectral density in order to conform to FCC requirements. At the receiver of MB-OFDM system needs to use of a technique called as OverLap-and-Add (OLA). Which maintain the circular convolution property and take the multipath energy of the channel? In this paper, the authors proposed a method of performing overlap-and-add length for zero padded suffixes.
