Method and System for Dynamic Spectrum Access Using Specialty Detectors and Improved Networking

A method of operating a dynamic spectrum access-enabled device, said method comprising:

• operating a detector to detect a non-cooperative signal in a first channel, the detector comprising an amplitude probability distribution (APD) detector, a locally-optimum Bayesian detector (LOBD), or a combination thereof;
• and
• selecting a channel for use by the dynamic spectrum access-enabled device based on the presence or absence of the non-cooperative signal in the first channel as determined by the detector.

A device comprising:

• a dynamic spectrum access module to coordinate communication with at least one cooperative dynamic spectrum access-enabled device;
• and
• a detector comprising an amplitude probability distribution (APD) detector, a locally-optimum Bayesian detector (LOBD), or a combination thereof.

A dynamic spectrum access (DSA)-enabled device configured to communicate concurrently with a second DSA-enabled device in a first DSA-enabled network and a third DSA-enabled device in a second DSA-enabled network.

A dynamic spectrum access-enabled device comprising:

• a first transceiver to operate on a first channel in a first dynamic spectrum access-enabled network;
• and
• a second transceiver to operate on a second channel in a second dynamic spectrum access-enabled network, the second channel being different than the first channel.

A system comprising:

• a plurality of dynamic spectrum access-enabled devices including devices from a plurality of non-cooperative dynamic spectrum access-enabled networks, each of the plurality of devices configured to refrain from transmitting during a first time period, the first time period being synchronized among the plurality of devices;
• and
• at least one of the plurality of devices including a sensor module to detect spectrum use by a device not in the plurality of devices that is non-cooperative with each of the networks during the first time period, and to detect spectrum use by a cooperative device not in said plurality of devices during a second time period, the second time period not coinciding with the first time period.

A dynamic spectrum access (DSA)-enabled device comprising:

• a first circuit causing the device to refrain from transmitting during a first time period, the first time period being synchronized among a plurality of other DSA-enabled devices in a plurality of dynamic spectrum-access enabled networks, each network being non-cooperative with at least one of the other networks;
• and
• a second circuit to sense at least one channel to detect spectrum use by at least one cooperative DSA-enabled device during a second time period, the second time period not coinciding with the first time period.

A method of coordinating dynamic spectrum access, the method comprising:

• scheduling a first time period during which a plurality of devices in a plurality of dynamic spectrum access networks refrain from transmitting, the first time period being synchronized among the plurality of devices;
• and
• during a second time period, sensing at least one channel to detect spectrum use by at least one cooperative device not in the plurality of devices on the at least one channel, the second time period not coinciding with the first time period.
