Abstract
A lens antenna array system is provided that includes a plurality of communication links. The lens antenna array system uses beam index modulation to select an active subset of communication links from the plurality of communication links. The selection of the active subset of the communication links constitutes the transmission of a digital word.
Claims20
A method of wireless communication for a lens antenna array system, comprising:
- selecting a first subset of transmit antennas from an array of transmit antennas arranged in a focal region of a first lens;
- transmitting from each transmit antenna in the first subset of transmit antennas to form a plurality of first RF signals that are directed through the first lens toward a second lens for a first symbol interval;
- selecting a second subset of transmit antennas from the array of transmit antennas;
- and
- transmitting from each transmit antenna in the second subset of transmit antennas to form a plurality of second RF signals that are directed through the first lens towards the second lens for a second symbol interval.

A lens antenna array system, comprising:
- an array of transmit antennas arranged in a focal region of a first lens;
- an array of receive antennas arranged in a focal region of a second lens;
- and
- one or more processors coupled with the array of transmit antennas and the array of receive antennas, wherein the one or more processors are configured to:
- select a first subset of transmit antennas from the array of transmit antennas;
- transmit through the first subset of transmit antennas to form a plurality of first RF signals that are directed through the first lens toward the second lens for a first symbol interval;
- select a second subset of transmit antennas from the array of transmit antennas;
- and
- transmit through the second subset of transmit antennas to form a plurality of second RF signals that are directed through the first lens towards the second lens for a second symbol interval.
