Abstract
Abstract:- Nowadays, low-complexity, high speed filter bank is an important concept for wireless communication applications such as spectrum sensing and channelization etc. In signal processing, a filter bank is an array of band pass filters that separates the input signal into multiple components, each one carrying a signal. In reconfigurable high speed filter bank, the bandwidth and center frequency of sub-bands can be varied with high frequency resolution. This is achieved with an improved Modified frequency transformation-based variable digital filter (MFTVDF). This low-pass MFT-VDF offers unabridged control over the cutoff frequency on a wide frequency range. The work deals with the interfacing of MFT-VDF with orthogonal frequency division multiplexing (OFDM) wireless application. In thiss dissertation, orthogonal frequency division multiplexing (OFDM) is used which is a combination of modulation & multiplexing. It is multi-carrier high data transmission scheme which supports 4G and has tremendous scope in the field of wireless communication. Unipolar communications systems can transmit information using only real and positive signals called as Flip-OFDM technique it is originally designed for optical communication to obtain error free transmission of data signal. Using MFT-VDF filter bank in OFDM side lobes in the signals are removed and achieved error free output and the design example shows that the RFFB is easy to design and offers substantial savings in gate counts over other filter banks.
Keywords- Keywords:- Orthogonal frequency division multiplexing (OFDM), reconfigurable filter bank, flip-OFDM, variable digital filter (VDF).
