Novel Digital Signal Processing and Detection Techniques.

Abstract

A number of results were obtained during the period 1 August 1979 to 30 July 1980. Studies were made of the implementation of narrowband digital filters with reduced roundoff error and limit cycle oscillations. Bounds on limit cycles of second order filters were derived for filters using error spectrum shaping. The performance of two sequential signal detectors were analyzed. A schemee for the computer generation of random sequences with a specified first order distribution and a specified autocovariance function is proposed and analyzed. A delta modulation like sampled analog filter structure is developed. The filter uses only coefficients O,+1, and -1, and can be fabricated as a programmable CCD filter. Work has begun on a further refinement of narrowhead spectrum analysis by direct decimation and on the use of recursive filters for decimation and interpolation.
