Multiple Signal Detection and Measurement Using a Configurable Wideband Digital Receiver

摘要

A configurable wideband digital receiver with multiple signal detection capability is presented. The implementation of multiple signal detection scheme is often a challenge due to the timing and hardware constraints. The efficient multiple detection scheme presented in this paper employs hardware reuse by effective configuration and detects multiple signals before the next set of buffered data arrives forprocessing. Performance evaluation of the configurable receiver to detect up to five signals, their maximum attainable instantaneous dynamic range (IDR) and frequency detection error analysis are presented.
