Abstract

This paper presents an FPGA solution for a high-speed front-end digital receiver of an Electronic Support Measures (ESM) system. An LMS-based adaptive predictor has been chosen to improve the signal-to-noise ratio (SNR) of the received radar signals. Two fine-grained pipelined architectures based on the Delay LMS (DLMS) algorithm have been developed for FPGA implementation. This paper also highlights the importance of choosing a suitable filter architecture in order to utilise FPGA resources resulting in a more efficient implementation. FPGA implementation results, including timing and area, are given and discussed.
