1. A method for facilitating at least one of wireless data communication and energy transfer using distributed beamforming in a wireless network, the method comprising:
implementing a plurality of transmitter nodes communicatively coupled with a user device in the wireless network;
receiving, by a receiver of the user device, a plurality of transmission signals corresponding to the plurality of transmitter nodes being in an orthogonal multiple access communication at the control data transmission stage;
selecting, by a processor of the user device, one of the transmission signal, amongst the plurality of transmission signals, as a reference transmission signal for computing a phase-shift for the remaining transmission signals of the plurality of transmission signals, wherein the phase shift and signal strength for each of the remaining transmission signals is determined by:
applying one or more predetermined phase-shift values upon each of the remaining transmission signals;
determining a beamforming gain for each of the remaining transmission signals with respect to the reference signal based on the applied one or more predetermined phase shift values, wherein the beamforming gain indicates the signal strength of each of the corresponding signal after being beamformed at one or more time instances corresponding to the one or more predetermined phase-shift values when applied;
selecting at least one predetermined phase-shift value corresponding to each transmitter node, amongst the one or more predetermined phase-shift values, having a maximum beamforming gain, thereby indicating the optimum phase shift for that transmitter; and
facilitating, by the processor of the user device, at least one of the wireless data communication and energy transfer from the plurality of transmitter nodes with the receiver of the user device by enabling each of the plurality of transmitter nodes to transmit data or energy simultaneously, at the predetermined phase-shift computed by the receiver and fed back to the transmitter, thereby achieving the beamforming gain.
