Abstract
A scalable algorithm may be used for determining beam/nullforming weights with minimal computation and minimal coordination between elements or subarrays. The algorithm may beamform large numbers of elements without channel state information and without knowing the signal of interest. The algorithm may optimize the signal-to-interference-plus-noise ratio of signals received at an array. The algorithm may remove the requirement for explicit channel state information (CSI) or for iterative co-estimation of CSI, remove the requirement for coordination with or knowledge of signals transmitted from null targets, and/or remove the requirement for knowledge of the number of targets by estimating and optimizing overall SINR, rather than jointly optimizing each received signal. The algorithm interprets the N-element arrays view of the signal-to-interference-plus-noise ratio as a N-dimensional gradient ascent. The search explores this N-D space to find a direction of ascent and applies a simultaneous search and track loop.
