Let MultiBand-OFDM Modified By Wavelet


This paper throws light on elevating the performance of MB-OFDM by diverse techniques. The initiative was that the wavelet transform altered the place of FFT and IFFT. The use of the wavelet transform can be ascribed to the fact that it counteracts various types of interference. Implementation of various modulation techniques refines the performance. The order of the wavelet transforms used should remain conducive to establish it as an efficient system for high data rates. As an outcome of noise the output of the channel is erroneous. Hence error control codes are utilized which aims at the removal of error from the transmitted bits. Further to achieve diversity space time block codes are concatenated with FEC codes.
