Time Efficient Structure for DFT Filter Bank

Abstract

Conventional filter bank based spectrum sensing methods employ uniform Discrete Fourier Transform Filter Bank (DFTFB). But the complexity with this is very high and the structure is inefficient since it remains idle for most of the time. This paper proposes a time efficient DFTFB employing Polyphase decomposition for each of filters in the DFT filter bank. Proposed structure also provides a tight control over per-channel frequency response which is critical for many of applications to achieve the specified level of performance
