摘要：An all-digital transmitter (ADT) is provided. The ADS includes a basebandinterface configured to store and transmit an (baseband) input signal at a correspondingfrequency band, a polyphase finite impulse response filter configured to receive and

convert the baseband input signal into different phases, a digital upconverter configuredto upconvert each of the different phase baseband input signal to a predeterminedcarrier frequency in a digital domain, a set of multi-core 2-dimensional network-resonantdigital plane wave beamfilters, wherein each of the multi-core 2D NR-DPW beamfilters isconfigured to transmit the upconverted baseband input signal by a target angle, a multi-core delta-sigma modulator configured to encode the upconverted input signal intopulsating signals, and a serializer configured to serialize the encoded pulsating signalsinto a RF bitstream.
