An all-digital transmitter (ADT) is provided. The ADS includes a baseband interface configured to store and transmit an (baseband) input signal at a corresponding frequency band, a polyphase finite impulse response filter configured to receive and convert the baseband input signal into different phases, a digital upconverter configured to upconvert each of the different phase baseband input signal to a predetermined carrier frequency in a digital domain, a set of multi-core 2-dimensional network-resonant digital plane wave beamfilters, wherein each of the multi-core 2D NR-DPW beamfilters is configured to transmit the upconverted baseband input signal by a target angle, a multi-core delta-sigma modulator configured to encode the upconverted input signal into pulsating signals, and a serializer configured to serialize the encoded pulsating signals into a RF bitstream.
