Abstract: A method and system for beamforming a multi-element array using time delays is provided. The array includes transmit array elements and receive array elements. Each of the array elements includes a processor. Modulation and demodulation functions are performed at the processors of each array element. The modulation and demodulation functions utilize receive time offsets and phase shifts, and transmit time offsets and phase shifts, respectively. The receive time offsets and phase shifts, and the transmit time offsets and phase shifts are determined by a central processing unit in order to beamform received signals and transmitted signals, respectively. The array elements are arranged in a daisy chain fashion in order to facilitate communication of control parameters, communication of bits to be transmitted and distributed combining of demodulated baseband samples from one array element to another and communicating the combined samples to the central processing unit.
