Smart meters in smart grid provide services such as meter information for billing, health monitor, phasor measurement, weather sensing and load characterization with outage detection and restoration. Communication between the load and the base station over smart grid is undertaken or monitored by smart meter. OFDM based communication module is an integral part of smart meter. In this paper, Dual Tree Complex Wavelet Transform (DTCWT) based Multi Band Orthogonal Frequency Division Multiplexing

Software reference model based on DTCWT, DWT, FFT and NCO are developed for comparison. The proposed DTCWT-OFDM model achieves 17dB improvement at 10-4 BER over that of other OFDM schemes. The time invariant property of dual tree wavelet also ensures improvement in BER performances. The reconfigurable down convert and up converter is reconfigurable and hence is designed for MBOFDM.
