Abstract
A method includes determining one or more delay values and one or more phase shift values for generation of multiple desired frequency-dependent analog beams. The method also includes configuring one or more true-time delay (TTD) elements and one or more phase shifters of a transceiver based on the one or more delay values and the one or more phase shift values, the transceiver having one or more radio-frequency (RF) chains connected to multiple antennas via the one or more TTD elements and the one or more phase shifters. The method also includes operating the transceiver to generate the multiple desired frequency-dependent analog beams.
