    Software radios are emerging as platforms for multiband multimode personal communications systems. Radio etiquette is the set of RF bands, air interfaces, protocols, and spatial and temporal patterns that moderate the use of the radio spectrum. Cognitive radio extends the software radio with radio-domain model-based reasoning about such etiquettes. Cognitive radio enhances the flexibility of perso... View full abstract»

    Among the various tasks performed by software radios is the reconfiguration of the error control coding algorithm to match the requirement of the radio personality. In the digital radio processor, proper assignment of tasks between DSPs and FPGAs provides performance improvements over the use of DSPs alone. Error control coding functions are good candidates to reside on the FPGA side of this funct... View full abstract»

    There has been an emerging interest in using ATM for wireless transmissions. Because ATM is primarily designed for an essentially error-free environment, in the wireless context the sources of errors and their consequences must be thoroughly understood. While this concern is valid in any network, it takes on a new, more central role in the wireless environment, where error bursts as expected to be... View full abstract»
