Abstract
A system and method for cognitive communication device operation. In accordance with the system and method, a node (102, 106, 107) that communicates in a wireless multihopping communication network (100) uses a receiver (302, 402, 502, 602) to acquire a digital sample of a communication signal, and extracts at least one feature of the digital sample. The node (102, 106, 107) employs a classifier (306, 406, 506) to determine the signal type, and a transmitter (108) to send feature vectors including information representing the signal type to other nodes (102, 106, 107) in the network (100).
Claims23
A method for performing distributed signal classification within a wireless multi-hop communication network, the method comprising:
- operating each of a plurality of multi-hop nodes within the wireless multi-hop communication network to:
- receive at least one respective signal and acquire a sample of the signal;
- extract at least one feature of the signal from the sample;
- assign a feature vector to the signal based on the at least one feature;
- classify the signal the signal as a certain type of signal based on the at least one feature;
- change an operation of the multi-hop node based on the signal classification;
- and
- transmit the feature vector including the signal type to other multi-hop nodes in the wireless multi-hopping communication network.
A node, operating in a wireless multi-hop communication network having a plurality of nodes, the node comprising:
- a receiver, for receiving at least one signal and acquire a sample of the signal;
- a feature extractor, for extracting at least one feature of the signal from the sample;
- a classifier, for classifying the signal as a certain type of signal based on the at least one feature and for assigning a feature vector to the signal based on the at least one feature;
- a decision component, for instructing the node to change an operation of the node based on the signal classification;
- and
- a transmitter, for transmitting to each of the other nodes, the feature vector including the signal type.
