ABSTRACT

ABSTRACT:

This seminar presents a segmented matched filter (SMF) used to perform code-phase acquisition in a direct sequence spread spectrum system. Conventional matched filters perform fast acquisition in the presence of high co-user noise, but are unable to handle carrier frequency offset (Doppler). Segmenting the filter increases tolerance to Doppler. This seminar describes a mixed signal ASIC that has modest hardware complexity when compared with an all-digital implementation. The seminar describes a 512-chip SMF design and reports on the architecture and testing of the prototype IC.

Dr. Bolton's research experience has been in the areas of multiple-valued logic circuits, computer-aided design systems, and pattern recognition. In particular he has carried out work on Application Specific Integrated Circuits (ASICs) in the areas of CDMA Code-phase Acquisition, ECG processing, Viterbi decoding, and Canonical-Signed Digit code filters. He has developed software for use with standard cell libraries for integrated circuit design software. He is particularly interested in the area of minimization and synthesis of multiple-valued logic functions. Dr. Bolton is the President of Professional Special System Technologies Incorporated a member of the Association of Professional Engineers and Geo-Scientists of Saskatchewan. and a member of the IEEE.
