Abstract
An example device includes antennas to receive wireless signals from a wireless transmitter and to output radio frequency signals based upon the wireless signals that are received, low noise amplifiers coupled to the antennas to amplify the radio frequency signals, and a receiver stage to generate, based upon the radio frequency signals, digital representations of the wireless signals that are received via the antennas and to determine a measure a wireless channel parameter from the digital representations of the wireless signals.
Claims20
A method comprising:
- activating, by a processing system including at least one processor, a first plurality of low noise amplifiers that is coupled to a first plurality of antennas;
- receiving, by the processing system from a transmitter, a first plurality of wireless signals via the first plurality of antennas and the first plurality of low noise amplifiers;
- determining, by the processing system, a first measure of a wireless channel parameter based upon the first plurality of wireless signals that is received;
- deactivating, by the processing system, the first plurality of low noise amplifiers;
- activating, by the processing system, a second plurality of low noise amplifiers that is coupled to a second plurality of antennas, wherein the second plurality of antennas comprises different antennas from the first plurality of antennas;
- receiving, by the processing system from the transmitter, a second plurality of wireless signals via the second plurality of antennas and the second plurality of low noise amplifiers;
- and
- determining, by the processing system, a second measure of the wireless channel parameter based upon the second plurality of wireless signals that is received.
An apparatus comprising:
