Low power design for baseband signal processing of broadband mobile communications

摘要

Low power implementation of baseband signal processing of mobile communications systems based on DS-CDMA is very important for practical applications. In the first phase of 3G mobile communications such as W-CDMA systems, the chip rate is not high, but it will become very higher in the second phase or 4G systems. The high chip rate requires high -speed matched filter to carry out dispreading operations, which increases consumption power. This paper presents the design for a matched filter with low consumption power.
