Patent ID: 8712333

Claim:
A system comprising: a sensing module configured to sense an interference signal in a wireless channel, determine whether the interference signal is noise or a modulated signal transmitted by a device, and attempt to determine, in response to the interference signal being a modulated signal, a modulation scheme of the modulated signal; a capacity determination module configured to determine capacities of the wireless channel to transmit data using a plurality of modulation schemes, wherein in response to the sensing module being able to determine the modulation scheme of the modulated signal, the plurality of modulation schemes includes the modulation scheme used by the device to modulate the modulated signal, and wherein in response to the sensing module being unable to determine the modulation scheme of the modulated signal, the plurality of modulation schemes includes one or more modulation schemes that can be used by the device to modulate the modulated signal; and a selection module configured to select, based on the capacities of the wireless channel, one of the plurality of modulation schemes to transmit data over the wireless channel.
