The Orthogonal Frequency Division Multiplexing (OFDM) is a parallel transmission scheme. It has attained the high data rate by splitting the data stream into a number of low-rate Sub-Carriers (SC) instead of utilizing one carrier at a high rate. OFDM have been around 1960s. This technique is mainly used in Digital Audio/Video Broadcast (DAB/DVB), wireless LAN (802.11a and HiperLAN2) and broadband wireless (802.16). In this design, the pipelined implementation of OFDM model is designed and it's used in wireless LAN IEEE 802.11a.
