Indoor positioning has become a hot research topic due to a plethora of interesting applications ranging from emergency responder tracking to location-based services. In this work we focus on the problem of network localization also sometimes called collaborative localization where a network of nodes is to be localized using both connections to anchors (when they exist) and connections between unlocalized...
Adaptive bit-interleaved coded modulation (ABICM) is attractive for rapidly varying mobile radio channels due to its robustness to imperfect channel state information (CSI) at the transmitter. Novel ABCIM method based on the expurgated bound is proposed. This method improves upon previously investigated ABICM techniques since it is able to maintain the target bit error rate for diverse CSI conditions...
Multicarrier code-division multiple access (MCCDMA) system with adaptive frequency hopping (AFH) has attracted attention of researchers due to its excellent spectral efficiency. A suboptimal water-filling (WF) channel allocation algorithm was previously proposed for the reverse link of this system. To overcome the limitations of the WF algorithm in the presence of fading-induced near-far problem,...
