In interference-limited wireless cellular systems, interference avoidance and interference averaging are widely adopted to combat co-channel interference. In different types of wireless networks, these two basic frequency planning methods are implemented under variable system deployment strategies. With respect to the IEEE 802.16 OFDMA network, interference(More)
Traditional admission control algorithms are based on bandwidth or channel reservation policy, which may be incompetent in IEEE 802.16e OFDMA systems for two reasons: (1) WiMAX system supports dynamic and flexible resource allocation, and (2) there exists a fundamental tradeoff between bandwidth resource and power resource. In this paper, we propose a novel(More)
A preliminary Chinese DNA database has been constructed by the analysis of samples from 2,211 Han Chinese in Liaoyang City, northeast China. Thirteen autosomal tetranucleotide short tandem repeats (STRs) widely used in forensic identification were selected for the DNA profiling, together with the X-Y homologous gene Amelogenin for sex determination. Only(More)
Efficient network selection and call admission control (CAC) strategies are the key components of the next generation heterogeneous wireless networks (HWN). In this paper, we propose a distributed uplink call admission control and network selection scheme for hybrid CDMA-OFDMA networks, which aims to efficiently utilize the overall radio resource of the(More)
The crucial contribution of the paper is the novel saturated throughput analysis of the IEEE 802.11 Distributed Coordination Function (DCF) in the presence of hidden stations. This approach involves a novel analytical model that is an extension to previous works by other authors which provide Markov chain analysis to IEEE 802.11 DCF. Hidden stations cause(More)
