概要 This paper presents a design for a low-power digital matched filter (DMF) applicable to Wideband-Code Division Multiple Access (W-CDMA), which is a Direct-Sequence Spread-Spectrum (DS-SS) communicatio...n system. The proposed architectural approach to reducing the power consumption focuses on the reception registers and the correlation-calculating unit (CCU), which dissipate the majority of the power in a DMF. The main features are asynchronous latch clock generation for the reception registers, parallelism of the correlation calculation operations and bit manipulation for chipcorrelation operations. A DMF is designed in compliance with the W-CDMA specifications incorporating the proposed techniques, and its properties are evaluated by computer simulations at the gate level using 0.18-μm CMOS standard cell array technology. The results of the simulations show a power consumption of 9.3 mW (@15.6MHz, 1.6V), which is only about 30 % of the power consumption of conventional DMFs.続きを見る
