Abstract

An apparatus for communications comprises a sample buffer, a beamformer and a processor. The sample buffer is configured to buffer respective subsets of digital sample streams obtained by converting analog signals from an antenna array. The analog signals corresponding to radio frequency signals received by the antenna array. The respective subsets extend across a portion of a duration. The portion is shorter in time than the duration. The respective subsets of the digital sample streams are time-synchronized with one another. The beamformer is configured to apply, to the digital sample streams extending across the duration, beam weights to the digital sample streams to obtain one or more beam signals that extend across the duration. The processor is coupled with the sample buffer. The processor is configured to determine a spatial characteristic for the radio frequency signals based at least in part on the respective subsets of the digital sample streams.
