Issue Date: | 2016 | Volume: | Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy VIII | Editors: | Holland, Wayne S.; Zmuidzinas, Jonas | Series: | PROCEEDINGS OF SPIE | Number: | 9914 | First Page: | 99143D | Abstract: | SETI, the Search for ExtraTerrestrial Intelligence, is the search for radio signals emitted by alien civilizations living in the Galaxy. Narrow-band FFT-based approaches have been preferred in SETI, since their computation time only grows like N*lnN, where N is the number of time samples. On the contrary, a wide-band approach based on the Kahrunen-Lo`eve Transform (KLT) algorithm would be preferable, but it would scale like N*N. In this paper, we describe a hardware-software infrastructure based on FPGA boards and GPU-based PCs that circumvents this computation-time problem allowing for a real-time KLT. | Conference Name: | Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy VIII | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/25005 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9914/1/A-real-time-KLT-implementation-for-radio-SETI-applications/10.1117/12.2232347.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510602076 9781510602083 |
