The design of generalized modulated filter banks and it's fast implementation in the B3G system

The design of the generalized DFT modulated filter banks employed in the generalized multi-carrier time division duplex hybrid multiple access (GMC-TDD-xDMA) system is investigated in this paper. A concise fast implementation of complex valued oversampled generalized DFT filter banks, which adapt to arbitrary integer sample rate, is derived in time domain by this paper.
