Abstract: | A weight control algorithm that may be used in a two-element adaptive array to protect a desired signal from an interference signal is described. 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. |
