A new algorithm of digital matched filter with a segment processing method
In this paper, a novel segment processing matched filter algorithm is proposed by optimizing the differential digital matched filter (DDMF) structure. According to the new architecture, the computation complexity of DMF can be reduced to approximately 30% of that of the DDMF for fixed coefficient PN sequence. To further reduce the area and power consumption, several strategies have been employed. This design was successfully tested as a component for an acquisition circuit to be used in Global Positioning System (GPS) receiver (Braasch and van Dierendonck, 1999), and was able to operate at up to 100MHz
