In mobile multihop communications, diversity technique is important since the channel between mobile terminals may suffer from effects of fading and the routes between terminals are normally created through several hops. Space-time code using multiple transmit antennas is effective countermeasure for fading. For terminals which have only one antenna due to(More)
This paper proposes a Multi-hop Radio Access Cellular (MRAC) scheme for achieving both highspeed/high-capacity and good area coverage in fourth generation mobile communications systems. In this scheme, we assume two kinds of hop stations, one is a dedicated repeater station installed at a good propagation location such as a rooftop, and the other is a user(More)
Tubulointerstitial damage plays a crucial role in the progression of kidney diseases, including diabetic nephropathy (1). Among several distinct types of fatty acid– binding protein (FABP), liver-type FABP (L-FABP) is abundantly expressed in hepatocytes and constitutively expressed in proximal tubular cells of the kidney (2). L-FABP incorporates(More)
The important issue of an adaptive scheduling scheme is to maximize throughput while providing fair services to all users, especially under strict quality of service requirements. To achieve this goal, we consider the problem of multiuser scheduling under a given fairness constraint. A novel Adaptive Fairness and Throughput Control (AFTC) approach is(More)
In this paper, Pareto optimal multi-user transmission scheduling in a system comprising of one source, one relay, and two destinations is discussed. To achieve proportional fairness among users in multi-user case, a scheduling scheme for a hybrid of full- and half-duplex relaying (FHDR) is proposed in this paper, which extends a transmission scheduling for(More)
