Abstract

Multirate filter banks have become excellent solution for future wireless communication system. Filter bank based multicarrier system provides high spectral efficiency through removal of redundant information resulting in efficient use of available spectrum. In multicarrier communication system, filter bank based transmultiplexer (TMUX) having same analysis and synthesis filter bank is employed. Efficient utilization of the available limited frequency spectrum, calls for on-board signal processing to perform flexible frequency-band reallocation (FFBR).This paper introduces a uniform TMUX which is the uniform band structure in which all the incoming data signals are assumed to have the same sampling rates and are upsampled at the same integer factor and thus, achieves nearly perfect reconstruction.
