摘要： A wireless communication network is provided in which a plurality of radio devices achieve frequency diversity. By utilizing cognitive capability within the radio devices to iteratively select frequency sets, a lowest cardinality frequency set is generated and used to communicate amongst the plurality of radio devices. Each radio device can have different hardware, as the iterative selection of frequency set can take into account the different hardware capabilities of the radio devices.

摘要： Systems and methods for managing power consumption in a device include toggling an ON-OFF setting of apparatus, which controls a carrier detector. The toggling is carried out according to a first duty cycle having a fixed OFF-time duration and a first dwell time having a first dwell time duration during which the carrier detector performs radio frequency carrier detection function. The device receives at least one input that affects the radio frequency carrier detection function, and the first duty cycle is changed to a second duty cycle. The toggling is carried out according to the second duty cycle, which has the same fixed OFF-time duration of the first duty cycle and a second dwell time having a second dwell time duration that is longer than the first dwell time duration, during which the radio frequency carrier detection function is performed.

摘要： A method of dynamically allocating RF communication channels to a wireless communication device (102). A plurality of dynamic spectrum allocation (DSA) channels (222, 224) can be identified. The DSA channels can be channels that are available to a non-incumbent user to be used for RF communications. Based on at least one required channel parameter, a DSA channel can be selected as a first channel to allocate to the wireless communication device. At least a second channel can be selected to allocate to the wireless communication device based on a spectral relationship between the first channel and the second channel to ensure that the first and second channels are separated by at least a minimum required frequency separation (216).
