摘要

A three gigasample per second (GSPS) digital wideband receiver that operates in a 1.25-GHz instantaneous bandwidth (IBW) is proposed. In addition to building such systems, offloading of computation-intensive tasks to a combination of specialized hardware accelerators such as graphics processing units (GPUs) and field-programmable gate arrays (FPGAs) to increase the overall receiver's dynamic performance is analyzed. The receiver detects up to 15 signals with a maximum attainable instantaneous dynamic range (IDR) of 62.5 dB before the next set of data arrives for processing.
