Anticipative Maximin Adaptive-Array Algorithm for Frequency-Hopping Systems

摘要

The anticipative maximin algorithm is a blind adaptive-array algorithm that exploits both the spectral and temporal characteristics of frequency-hopping signals. The anticipative maximin algorithm fuses a new form of anticipative processing with an improved version of the maximin algorithm to enable the cancellation of partial-band interference within a hopping band. Major advantages are that the anticipative maximin algorithm requires neither training sequences, directional information, nor decision-directed adaptation. Details of the design of the anticipative maximin processor are presented. Extensive simulation experiments confirm the effectiveness of the algorithm against partial-band interference under a variety of scenarios.
