Implementation of an adaptive processor by modern spectral estimation techniques
Abstract
Modern spectral estimation techniques such as Burg's maximum entropy method (MEM) can significantly improve the performance of adaptive processors. A real-time digital adaptive processor has been developed at the RADC Signal Processing Laboratory Test Facility to test the applicability of these techniques. The processor, configured as a reprogrammable 'general-purpose' computer in order to facilitate the comparison of alternate algorithms, is currently programmed for Burg's algorithm. The design trades, the theoretical performance, and the implemented processor are described. Computer simulation has shown that the MEM fulfills the speed requirement.
