Beamforming systems and methods

摘要

A first network device including a receiver, a steering module, and a transmitter. The receiver is configured to receive a first signal from a second network device. The first signal is transmitted from the second network device using a first modulation system. The steering module is configured to generate a steering matrix based on the first signal. The transmitter is configured to transmit a second signal using the steering matrix to the second network device. The second signal is transmitted using a second modulation system. The first and second modulation schemes are selected from a group consisting of (i) a plurality of single carrier based modulation schemes and (ii) a plurality of orthogonal frequency division multiplexing based modulation schemes. The second modulation system is different from the first modulation system.

1. A first network device comprising:
a receiver configured to
receive a first signal from a second network device,wherein the first signal is transmitted from the second network device using a first modulation scheme, andwherein the first modulation scheme is selected from a group consisting of (i) a plurality of single carrier based modulation schemes and (ii) a plurality of orthogonal frequency division multiplexing based modulation schemes; a steering module configured to generate a steering matrix based on the first signal; and a transmitter configured to
transmit a second signal reusing the steering matrix to the second network device,wherein the second signal is transmitted using a second modulation scheme,wherein the second modulation scheme is selected from the group consisting of (i) the plurality of single carrier based modulation schemes and (ii) the plurality of orthogonal frequency division multiplexing based modulation schemes, andwherein the second modulation scheme is different from the first modulation scheme.
