Abstract
UWB (Ultra Wide Band) interference mitigation. A novel solution is presented whereby various piconet operable devices are operated to support a relatively structured interference pattern. The devices operate cooperatively (e.g., within multiple piconets that may be in relatively close proximity) such that undesirable symbol collisions generate relatively structured interference (e.g., a structured interference pattern). A piconet operable device (e.g., a communication transceiver or receiver) operating therein includes intelligence such that it may detect a symbol that has undergone an undesirable symbol collision. Then, after those symbols have been identified, they may be modified appropriately so the overall performance of the piconet may be kept at a high performance level. For example, those symbols having an energy (or power) above a predetermined threshold (such as an expected energy level or a power level) may be appropriately de-weighted.
