Design and Implementation of OFDM Transceiver for ISI Reduction using Sinc Filter

Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission, where a single data stream is transmitted over a number of lower ratesubcarriers.4G and other wireless systems are currently hot topics of research and development in the communication field. Orthogonal frequency division multiplexing (OFDM) is the most commonly used modulation scheme for high data rate wireless transmission .In this paper, an OFDM Transceiver has been reduced the noise and to increase the throughput for future wireless networks .Here the data rate is increased by implementing a 1024-point parallelized FFT/IFFT Processor. In the modulation scheme sinc Filter is used for Noise Reduction. By this work we may obtain a throughput speed between 2 Gbps and 4Gbps.
