    摘要: A location technique is utilized within a wireless communication system where power measurements from various nodes are weighted to determine a node's location. An iterative location process is executed where as more and more nodes are heard from, a node will re-locate itself in order to improve location accuracy.

    摘要: A communication device includes a receiver that is capable of canceling in-channel interference. The receiver includes an antenna for receiving a wireless signal comprising in-channel components and an out-of-channel component, wherein the in-channel components comprise a desired component and an in-channel interference component. A first filter of the receiver filters the wireless signal by blocking at least a portion of the out-of-channel component to produce a first signal comprising the in-channel components, and at least a second filter of the receiver filters the wireless signal by blocking at least a portion of the in-channel components to produce a second signal comprising the out-of-channel component. An in-channel interference estimator of the receiver generates an in-channel interference estimation signal based on the second signal. And a combiner of the filter combines the first signal and the second signal to at least partially cancel the in-channel interference component of the first signal.

The wireless communication device includes an upsampled broadband multicarrier signal generator and multiple upsampled sidelobe signal generators. The upsampled broadband multicarrier signal generator receives a symbol stream and, based on the symbol stream, generates a broadband multicarrier signal comprising an in-channel signal and a first multiple out-of-channel sidelobes. Each upsampled sidelobe signal generator of the multiple upsampled sidelobe signal generators receives at least a portion of the symbol stream and, based on at least a portion of the symbol stream, generates an out-of-channel sidelobes to produce a second multiple out-of-channel sidelobes.

    摘要: A communication device and method of allocating spectrum resources in a communication system to protect data to be transmitted are disclosed. The communication channel resource is divided temporally to form regions. Data to be transmitted is separated into data portions. Each data portion is able to be transmitted over one of the regions. The data portions are prioritized based on the importance of the data portion. The regions are ranked based on the transmission reliability thereon. The prioritized data portions are mapped to the ranked regions such that more important data portions are mapped to more reliable regions and less important data portions are mapped to less reliable regions. The prioritized data is output temporally in order of importance to enable the mapping of the prioritized data.
