In this paper, interference mitigation through downlink power control is considered for macrocell Femtocell overlay. Specifically, the strong interference in the downlink from the home base station to a nearby macrocell user should be properly controlled such that the quality-of-service of both the macrocell user and the Femtocell users can be guaranteed. In this work, the fundamental capacity limitation...
Macro-diversity - all base stations decode cooperatively each received signal - can mitigate shadow fading, and increase the capacity of a spread-spectrum communication network. Assuming that a terminal's transmission power contributes to its own interference, the literature determines whether a vector of quality-of-service targets is feasible through a simple formula, which is insensitive to the...
Underwater acoustic channel (UACh) requires robust techniques to get high speed data transmission for reliable communication. This paper presents the adaptive transmission technique in conjunction with the maximal ratio combining (MRC) diversity technique to adapt the UACh fluctuation based on a statistical channel model. Simulation analysis shows that we can optimize the data rate allowing the transmit...
