Using FPGAs for Software-Defined Radio Systems: a PHY layer for an 802.15.4 transceiver

During the last decade, designers have used ASICs and DSPs to handle nearly all of the signalprocessing functions associated with radio communications. Latest generation of FPGAs are so powerful that they're now displacing both ASICs and DSPs in software-radio applications. Software radio is an emerging technology, aimed to build flexible radio systems, which are multiple-service, multi-standar...

Design and Implementation of Field Programmable Gate Array Based Baseband Processor for Passive Radio Frequency Identification Tag (TECHNICAL NOTE)

In this paper, an Ultra High Frequency (UHF) base band processor for a passive tag is presented. It proposes a Radio Frequency Identification (RFID) tag digital base band architecture which is compatible with the EPC C C2/ISO18000-6B protocol. Several design approaches such as clock gating technique, clock strobe design and clock management are used. In order to reduce the area Decimal Matrix C...

FPGAs: Re-Inventing the Signal Processor

FPGAs are increasingly being employed for building real-time signal processing systems. They have been used extensively for implementing the PHY in software radio architectures. This paper provides a technology and market perspective on the use FPGAs for signal processing and demonstrates FPGA DSP using an adaptive channel equalizer case study.

Interference Mitigation for WCDMA Using QR Decomposition and a CORDIC-based Reconfigurable Systolic Array

Abstract This paper presents implementation and performance of QR Decomposition based Recursive Least-Squares (QRD-RLS) for interference mitigation in Wideband CDMA (WCDMA). The implementation is carried on CORSAEngine which is a new Software-Defined Radio (SDR) processor developed by NEC Corporation and highly optimized for MIMO-OFDM systems. It is shown how QRD-RLS can be mapped on its rectan...
