Design of COFDM Transceiver Using VHDL
OFDM is combined with channel coding scheme i.e. FEC (Forward Error Correction) called CODED OFDM or COFDM is especially suitable for high speed environment because it provides data transfer at higher speed with reliable transmission. This paper is to design COFDM transceiver which operates with FEC, scrambling, block inter-leaver with conventional OFDM system to overcome the problem in wireless link i.e. ISI, ICI, fading etc. In this paper, COFDM transceiver designing details and simulation results are discussed after that COFDM modulator is compared with previous work which ensures present work is better than previous work.
