It is expected that the CSO’s observatory efficiency can be increased by weather-multiplexing highand low-frequency observations. We define schemes for multiplexing between Bolocam lowfrequency (150 and 275 GHz) and high-frequency (850 GHz) SHARC-II or heterodyne observations. The SHARC-II multiplexing scheme is a simple cut in τ225. The heterodyne multiplexing scheme makes use of the wide rang...

This paper studies the impact of long-range-dependent (LRD) traffic on the performance of reassembly and multiplexing queueing. A queueing model characterizing the general reassembly and multiplexing operations performed in packet networks is developed and analyzed. The buffer overflow probabilities for both reassembly and multiplexing queues are derived by extending renewal analysis and Beneš ...

Achieving statistical gains when multiplexing video streams, as in a video-on-demand (VOD) scenario, is difficult because of the stringent QOS demands and the selfsimilar nature of the traffic. This paper explores, through empirical simulation, the QOS, network utilization, and statistical characteristics of the aggregate traffic resulting from multiple independent MPEG video streams. In additi...

Significant effort in optical-fiber research has been put in recent years into realizing mode-division multiplexing (MDM) in conjunction with wavelength-division multiplexing (WDM) to enable further scaling of the communication bandwidth per fiber. In contrast almost all integrated photonics operate exclusively in the single-mode regime. MDM is rarely considered for integrated photonics due to ...

The non-deterministic nature of photon sources is a key limitation for single-photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single-photon yield without enhancing the output noise. Here the intrinsic statistical limit of an individual source is surpassed by spatially multiplexing two monolithic silicon-based correlated photon pair sources in the telecom...

A statistical multiplexing scheme in orthogonal downlinks is proposed to accommodate more downlink orthogonal channels than orthogonal codewords for mobile stations. The number of allocable downlink orthogonal channels depends on the average burstiness of the channels. The statistical multiplexing scheme is called here as the orthogonal code hopping multiplexing (OCHM). Since the OCHM uses a pr...

This paper studies link adaptation technique for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems with limited feedback. In order to utilize highly fluctuating MIMO channel efficiently and reliably, spatial mode switching between beamforming, diversity and multiplexing modes is needed. We propose mutual information effective SINR mapping (MIESM) me...

Single-exposure superresolved interferometric microscopy (SESRIM) by RGB multiplexing has recently been proposed as a way to achieve one-dimensional superresolved imaging in digital holographic microscopy by a single-color CCD snapshot [Opt. Lett. 36, 885 (2011)]. Here we provide the mathematical basis for the operating principle of SESRIM, while we also present a different experimental configu...

in this paper the problem of minimizing the total transmitting power subject to a fixedtotal bit rate in ofdm systems is considered. upper bounds on transmitting power and bit rate ofeach subcarrier can also be taken into account. in practice, the number of bits of each subcarriershould be integer and nonnegative. in this paper an analytical optimal solution is derived for thecase of assuming t...

A contemporary perspective on the tradeoff between transmit antenna diversity and spatial multiplexing is provided. It is argued that, in the context of most modern wireless systems and for the operating points of interest, transmission techniques that utilize all available spatial degrees of freedom for multiplexing outperform techniques that explicitly sacrifice spatial multiplexing for diver...
