The rapid growth of the wireless users in contemporary wireless networks requires more potential spectrum usage. As a result, spectrum bands are deemed to be getting congested. Conversely, the authorities have found that a quantity of frequency bands licensed to operators is under-utilized, and hence implies the inefficiency of spectrum utilization. The provisioning of Cognitive Radio (CR) enables...
To acquire weak signals GPS reiceiver requires longer observation intervals to accumulate sufficient energy from the signal of intermediate frequency. Full bit method avoids effects of the data bit modulation thereby preserves a longer coherent integration yet consumes too much time and resources. In this paper, an enhanced full bit method is proposed, which aims at speeding up the full bit acquisition...
Contemporary communication networks are expected to support multimedia services which require differentiated quality-of-services (QoS). To this end, many traffic scheduling schemes have been proposed and extensively studied. Recently, a hybrid scheduling discipline which integrates priority queueing and generalized processor sharing (GPS) has been emerging as a promising scheme for QoS differentiation...
