In this paper we present a new algorithm for mobile power updates in wireless CDMA systems. The algorithm in fact represents accelerated Jacobi iterations for mobile power updates of the algorithm popularly known as the DPC (distributed power control) algorithm. The new algorithm, with more rapid convergence, is obtained using Steffensen fixed-point iterations initialized by two Jacobi iteratio...

This paper describes a processor and an inter-processor communications interface integrated on a single chip for use in a distributed processing system. The system is based on work of the electronic systems design and parallel processing group at the Nottingham Trent University. The four main elements of the chip design are processor, memory, communication interface and packet routing switch al...

This paper presents a novel hardware architecture based on generalized Hebbian algorithm (GHA) for texture classification. In the architecture, the weight vector updating process is separated into a number of stages for lowering area costs and increasing computational speed. Both the weight vector updating process and principle component computation process can also operate concurrently to furt...

The diffuse X-ray scattering method has been applied to samples composed of SOPC, DOPC, DMPC, and POPC with added sugar, either sucrose, glucose, fructose, maltose, or trehalose. Several sugar concentrations in the range 200-500 mM were investigated for each of the lipid/sugar samples. We observed no systematic change in the bending modulus KC or in the tilt modulus Kθ with increasing sugar con...

Real time multi-channel sliding correlation processing is widely applied in underwater communication system or underwater positioning system. The traditional implementation in FPGA always employs parallel method which reduces the design work, however wastes considerable FPGA resources. This paper described a new kind of SOPC structure which based on AVALON bus, taken NIOS CPU as system controll...
