Abstract

A digital pre-processing chip is disclosed. The digital pre-processing chip comprises an analog interface for transmitting and receiving analog signals to and from a plurality of analog Radio Frequency (RF) chips, and a digital interface for transmitting and receiving digital signals to and from a baseband chip. The digital pre-processing chip further comprises a plurality of Analog-to-Digital Converters (ADCs) for converting a plurality of analog signals received via the analog interface to a plurality of RX digital signals, and a plurality of Digital-to-Analog Converters (DACs) for converting a plurality of TX digital signals to a plurality of analog signals to be transmitted to the plurality of analog RF chips via the analog interface. The digital pre-processing chip further comprises pre-processing circuitry configured to pre-process the plurality of RX digital signals received from the plurality of ADCs to form a pre-processed digital signal to be transmitted to the baseband chip via the digital interface. The pre-processing circuitry is further configured to pre-process a digital signal received via the digital interface to form the plurality of TX digital signals to be trans…
