Abstract

Band-pass sampling is one of the most important technologies in software radio. This paper analyzes the band-pass signal sampling theorem carefully. Considering the engineering implementation, it proposes an associated method for the selection of IF frequency and sampling frequency, which can achieve the optimal performance. It also introduces a design scheme about CDMA2000 multi-carrier digital IF receiver system. At last it applies the method to the design of CDMA2000 multi-carrier digital IF receiver, which validates the optimal method effective and feasible.
