Abstract:
A first device including a receiver, a steering module, and a transmitter. The receiver receives a first signal transmitted using a first modulation scheme from a second device. The steering module obtains a steering matrix from the first signal transmitted using the first modulation scheme from the second device. The transmitter transmits a second signal using a second modulation scheme to the second device by reusing the steering matrix obtained from the first signal transmitted using the first modulation scheme from the second device. The first modulation scheme and the second modulation scheme are selected from a plurality of orthogonal frequency division multiplexing based modulation schemes. The second modulation scheme is different from the first modulation scheme.
