Abstract

This document describes the design and implementation of a high fidelity instrumentation digital radio front-end, following the standard DRM "Digital Radio Mondiale" [1]. This approach meets the need of measurement equipment in the planning steps preceding digital radio commercial operation. The front-end captures AM band signal from an antenna, filters and digitizes a specific frequency channel by means of undersampling techniques, and transmits its samples in real time through an Ethernet network torwards a computer, namely back-end, which is responsible for demodulation. The design is intended to minimize hardware process as far as possible, in order to provide flexibility and minimize distortion. Procedures for remote configuration and status feedback of the front-end are specified as well.
