Method of transmission from multiple transmit chains based on a cost function for electromagnetic radiation

摘要

Embodiments of methods and apparatuses for transmission using a plurality of transmit chains based on a cost function for electromagnetic radiation are disclosed. One method is utilizing a plurality of chains, adjusting at least one of a phase or an amplitude of at least one of the transmit chains based on a cost function, wherein the cost function comprises a criterion for quality of reception at an intended receiver and a threshold for electromagnetic radiation.

1. A method of transmission from an electromagnetic signal transmitting device, comprising:
utilizing a plurality of transmit chains of the electromagnetic transmitting device to transmit electromagnetic signals; adjusting at least one of a phase or an amplitude of at least one of the transmit chains based on a cost function, wherein the cost function comprises:
a criterion for quality of reception at an intended receiver, wherein the intended receiver is located at least a far-field distance from the electromagnetic signal transmitting device;a threshold for electromagnetic radiation at a near-field distance from the electromagnetic signal transmitting device, wherein the near-field distance is greater than zero and less than the far-field distance.
