Abstract
An Advanced Antenna System (AAS) receiver and related methods are provided. According to one aspect an AAS receiver comprises a digital processing block of a Radio Frequency Integrated Circuit (RFIC). The digital processing block comprises an interface for communicating with a Central Unit (CU), and a plurality of Antenna Signal Processing Blocks (ASPBs), each receiving a digitized receive signal from a respective antenna element of an antenna array. Each ASPB comprises one or more receivers, each of which receives the signal from the respective antenna element, processes the received signal, and beamforms the processed signal to produce one or more data streams to be sent to the CU. Each ASPB also includes a narrowband receiver that processes an input signal (either the signal received from the respective antenna element or that signal after processing) to create a narrowband signal that is provided to the CU directly, without beamforming.
