Title: Adaptable Hybrid Filter Bank Analog-to-Digital Converters for Simplifying Wideband Receivers
Authors: Xu Liu;Wei Li;Jibo Wei;Longwang Cheng
Year: 2017
Publisher: IEEE
Abstract: The hybrid filter bank (HFB) has been considered as a promising solution for high-speed, high-resolution analog-to-digital conversion. In this letter, we propose an adaptable HFB architecture of which the conversion band can be adapted according to the frequency band of interest, e.g., the entire working band of a wideband receiver or a subband with an arbitrary spectrum position. Furthermore, we propose a strategy based on the adaptable HFB for a wideband receiver to efficiently fulfill different tasks. For spectrum sensing, the entire wideband conversion HFB is used. While for subband signal receiving, the subband conversion HFB is utilized. Examples show that compared with the existing HFB studies in which the wanted subband signal is extracted from the digitalized entire working band, the proposed strategy can significantly simplify the receiving process for subband signals, because the subband conversion HFB has a filtering effect on the input spectrum.
