In this paper, we describe a framework for exploring various multiplexing approaches in optical networks and evaluating their cost-eeectiveness. A comprehensive comparative study of two representative approaches, known as Path Multiplexing (PM) and Link Multiplexing (LM) 1, 2], is conducted with respect to on-line permutation scheduling. It is found that in many networks, PM is nearly as eeecti...

Spatial multiplexing or BLAST (Bell Labs Layered Space-Time) and space-time block-coding (STBC) are promise approaches that exploits the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work we evaluate the performance of a MIMO system that combines transmit diversity and spatial multiplexing schemes. We also propose two effective receiver st...

In this paper, we investigate high-capacity fiber-optic networks for real-time telemetry applications. The network topologies and related network components are analyzed for telemetry fiber-optic Local Area Network (LAN) and Metropolitan Area Network (MAN) as well as MAN internetworking with LANs. Two types of multiplexing techniques, namely, Wavelength Division Multiplexing and Time Division M...

Hadamard transform spatial multiplexing techniques are applied to laser densitometry in order to prevent the photo-induced degradation of sensitive materials. Photochemical and thermal degradations can often occur in point focused scanning laser densitometry. In spatial multiplexing, the excitation source is defocused and efficiently distributed throughout the sample, reducing local power densi...

Abstract. Future wireless communication systems require novel techniques to increase the bitrate, coverage and mobility. One of these techniques is spatial multiplexing and we have investigated the use of a CSP-based kernel in the implementation of a spatial multiplexing testbed. It turns out that the use of the CSP-based kernel not only provides a good way of system modeling, but also provides...

In this paper, we develop two analytic models for scheduling fork-join computations on distributed-memory multiprocessor system. The rst model allows for arriving tasks to multiplex processors with existing tasks, while the other model does not allow multiplexing. Both models assume that tasks block for I/O and that the overhead of rescheduling a task to another processor is prohibitive. We com...

Determining how neuronal activity represents sensory information is central for understanding perception. Recent work shows that neural responses at different timescales can encode different stimulus attributes, resulting in a temporal multiplexing of sensory information. Multiplexing increases the encoding capacity of neural responses, enables disambiguation of stimuli that cannot be discrimin...

Efficient utilization of the spectrum is the key challenges is multiplexing technology, and have OFDM is a transmission technique which ensures efficient utilization of the spectrum by allowing overlap of the spectrum by allowing overlap of carriers. It has various advantages like high spectral density, its robustness to channel fading, its ability to overcome several radio impairment factor su...

Divisor-Skip Wavelength Division Multiplexing (DS-WDM) ring is an optical interconnection network for workstation clusters or parallel machines which can connect various number of nodes easily using wavelength division multiplexing techniques. However, the wavelength-ordered routing algorithm proposed for the DS-WDM ring requires complicated processes in each router. Here, a new routing algorit...
