Digital weighted integrate-and-dump filter (WIDF) proposed for detection of weak rectangular-pulse signals corrupted by additive white Gaussian noise. Received signal first low-pass prefiltered, and samples taken at multiple of symbol frequency. Improved performance means lower sampling and processing rates used for given symbol rate, reducing cost of system.
