Software radio based re-configurable correlator/FIR filter for CDMA/TDMA receiver

Abstract

In this paper, a re-configurable architecture for both chip-rate de-spreading and FIR filtering is proposed. The proposed architecture can be configured as a chip matched filter, multi-code RAKE receiver, or an FIR filter. Since these modules are essential for CDMA/TDMA systems, we believe the proposed architecture is quite useful for CDMA/TDMA dual-mode receiver design.
