Power Optimization in Adaptive Array: A Technique for Interference Protection

摘要

This report describes a weight control algorithm that may be used in a 2-element adaptive array to protect a desired signal from an interference signal. The algorithm is a constrained gradient technique that either maximizes or minimizes array output power. It is shown that by choosing appropriately between minimization and maximization, a useful desired signal-to-interference-plus-noise ratio can be maintained at the array output over a wide range of signal powers.
