FEC and DWT Guided Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM)-Enriched Quality

J. Avila and K. Thenmozhi

Abstract:
For high data rate wireless applications over short distances, multiband OFDM proves to be the right contender. The concatenation of error control code for multiband OFDM cognitive radio system is analysed. Reed Solomon code and convolutional code are taken in to account for analysis. From the simulation results it can be inferred that because of the improved coding gain concatenated codes prove to be superior to single codes. As a supplementary, the fast Fourier transform and Inverse fast Fourier transform portion of the multiband OFDM systems are exchanged with the discrete wavelet transform and inverse discrete wavelet transform blocks respectively thus reducing the interferences drastically and as a result the overall bit error rate (BER) gets improved.
