in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

The capacity of mode-division multiplexing (MDM) systems is limited, for a given outage probability, by mode-dependent loss (MDL) and gain. Modal degrees of freedom may be exploited to increase transmission rate (multiplexing gain) or lower outage probability (diversity gain), but there is a fundamental tradeoff between the achievable multiplexing and diversity gains. In this Letter, we present...

Frame level H.264/MPEG encoded VBR video traffic is highly bursty in nature because of inherent coding techniques employed. Multiplexing traffic from many VBR sources results in smoothing of generated traffic from the multiplexer, and improves Statistical Multiplexing Gain (SMG). An efficient multiplexing methodology can greatly enhance resource utilization. Performance of multiplexer can be es...

Multiplexing is a method by which multiple analog message signals or digital data streams, coming from different sources are combined into one signal over a shared medium. In this paper, we present an overview of different multiplexing techniques in bandwidth utilization. We focus on the three well-known multiplexing technique used in bandwidth utilization which are Frequency-Division Multiplex...

A method of multiplexing holograms by rotating the material or, equivalently, the recording beams is described. Peristropic (Greek for rotation) multiplexing can be combined with other multiplexing methods to increase the storage density of holographic storage systems. Peristrophic multiplexing is experimentally demonstrated with Du Pont's HRF-150 photopolymer film. We multiplexed a total of 29...

There are three multiplexing schemes for Multi-Input MultiOutput (MIMO) channel sounder Time-division multiplexing (TDM), Code-division multiplexing (CDM) and Frequencydivision multiplexing (FDM). The purpose of this paper is comparison overview of multiplexing schemes for MIMO channel sounder. In this paper TDM, FDM and CDM techniques for MIMO channel sounding are considered. TDM, FDM and CDM ...

Space-time block codes (STBC) and spatial multiplexing (SM) are promising techniques that effectively exploit multipleinput multiple-output (MIMO) transmission to achieve more reliable communication and a higher multiplexing rate, respectively. In this paper, we study a practical design for hybrid scheme with multi-input multi-output orthogonal frequency division multiplexing (MIMOOFDM) systems...
