Abstract Orthogonal Frequency Division Multiplexing (OFDM) is a wireless data transmission based system. Modulation and De-Modulation are the most important technique in OFDM wireless communication scheme. A reconfigurable based modulation and demodulation technique improve the performance of OFDM system. The major aspire of this technique is achieving low power and high speed during the transmission of data in the OFDM system. Reconfigurable technique is varied from the adaptation technique. Adaptation does not improve the performance of the system, but reconfiguration technique improves the performance in various types. The proposed concept is introduced in OFDM based communication for performance and efficiency enhancements. This process is done in Xilinx simulation environment and ModelSim 6.3c.
