Abstract:
A matched filter bank comprising:a sampling and holding unit for sampling and holding successive input signals of a number of â€œmâ€  (m: integer not less than 2); a plurality of PN code registers of a number of â€œnâ€  (n: integer not less than 2), each said PN code register including a plurality of stages of number of â€œmâ€  for storing coefficient data, each said PN code register being a shift register with circulation; a plurality of groups of multiplication circuits of said number of â€œnâ€  corresponding to said PN code registers, each said group including a plurality of multiplication circuits of said number of â€œmâ€  corresponding to said stages of each said PN code register, each said multiplication circuit multiplying an output of one of said sampling and holding circuit and an output of one of said PN code register; and one or more adders for adding selectively outputs of said multiplication circuits of a number corresponding to a length of said coefficient data.
