In this paper we analyze various user assignment and scheduling policies for neigbouring femtocell networks. The trade-off between capacity maximization and fairness is investigated and a combined user assignment and proportional fair (PF) scheduling procedure for a femtocell gateway is proposed. The flexibility of the proposed architecture in terms of capacity and fairness is studied via various...
With the advances in optical technology, the span of a broadband access network using passive optical network (PON) technology can be increased from today's standard of 20 km to 100 km or higher, and thereby serve a lot more users. Such an extended-reach PON is known as SuperPON in the literature, and we call it a long-reach PON (LR-PON). A major challenge in LR-PON is that the propagation delay (for...
This paper presents a novel CMOS current feed-back inductive buffered trans-impedance amplifier (IBTIA) stage using the IBM 130 nm 8M2P CMOS process technology. Using the novel inductive buffer technique a 10 GHz bandwidth was achieved with a trans-impedance gain of ?? 47 dB?? without large gain peaking when compared to the inductive shunt peaking technique. In addition, the inductive buffer also...
MANET has been a hot research topic for quite a few years. The principal attractions of MANETs are related to the ease with which they can be deployed due to their infrastructure-less and decentralized nature. Applications for MANET range from military operations and emergency disaster relief, to community networking and interaction between attendees at a meeting. The challenge of MANETs is to design...
