Anticipative Maximum 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 ae that the anticipative maximin algorithm requires neither training sequences, directional information, nor decision-directed adaptation. The algorithm provides frequency compensation when the hopping spans a wide spectral band. The algorithm is derived and shown to converge. 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.
