A high-throughput array receiver has been developed that enables communication in radio frequency interference-rich environments with field programmable gate array (FPGA)-based frequency channelization and packetization. In this study, a real-time interference mitigation algorithm was implemented on graphics processing units (GPUs) contained in the data pipeline. The key contribution is a hardware and software pipeline for subchannelized wideband array signal processing with 150 MHz instantaneous bandwidth and interference cancellation with a heterogeneous, distributed, and scaleable digital signal processing (DSP) architecture that achieves 30 dB interferer cancellation null depth in real time with a moving interference source.<\/jats:p>","DOI":"10.3390\/s23146584","type":"journal-article","created":{"date-parts":[[2023,7,24]],"date-time":"2023-07-24T03:03:25Z","timestamp":1690167805000},"page":"6584","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Wideband Array Signal Processing with Real-Time Adaptive Interference Mitigation"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3959-585X","authenticated-orcid":false,"given":"Adam","family":"Whipple","sequence":"first","affiliation":[{"name":"Electrical & Computer Engineering, Brigham Young University, Provo, UT 84602, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9473-9652","authenticated-orcid":false,"given":"Mark W.","family":"Ruzindana","sequence":"additional","affiliation":[{"name":"Breakthrough Listen Project, U.C.
