We consider call admission and capacity management in a dynamically recon gurable network that carries a multitude of tra cs. Our approach is a heuristic capacity assignment algorithm designed to maximise an arbitrary pro t function. The algorithm is based on the concept of equivalent circuits, i.e. a given relationship between transmission capacities and call handling capabilities expressed as...

In the present work, we have combined Orthogonal Space-Frequency Block Coding (OSFBC) and Spatial Multiplexing (SM) in one transmission scheme for Orthogonal Frequency Division Multiplexing (OFDM) systems. In the combined transmission scheme, both spatial diversity and multiplexing benefits are possible to achieve. Simple Alamouti coding as the S-F coding across spatial multiplexing branches an...

In this paper, the potential of orthogonal frequencydivision multiplexing-code-division multiplexing (OFDM-CDM) combined with the pre-equalization is investigated. The codedivision multiplexing (CDM) component within an orthogonal frequency-division multiplexing (OFDM) system enables additional diversity in frequencyand time-selective mobile radio channels. While, by applying pre-equalization a...

Generating N single photons simultaneously is a formidable challenge due to the lack of deterministic single photon sources. Recent work [New J. Phys. 19, 063013 (2017] has proposed a relative multiplexing scheme that can enhance the N single photons probability with a minimum of active switching resources. We experimentally demonstrate relative temporal multiplexing on two photon sources with ...

In this paper, we study the Diversity-Multiplexing Tradeoff (DMT) of the Decode or Quantize and Forward (DoQF) protocol recently proposed in [1] for the half duplex single relay channel. Our results show that this static relaying protocol achieves the 2 by 1 MISO bound for multiplexing gains r < 0.25. The DMT of the classical non orthogonal Decode and Forward (DF) protocol is also derived. We s...

To predict AAL2 multiplexing performance, we derived bandwidth gain analytically using discrete Markov chain model for voice service and validated these results with a simulation. And we also performed detailed simulation for voice and data services in a concentrator. Based on the analysis, we find that there is no major benefit of AAL2 multiplexing in a concentrator. The benefit of AAL2 multip...

A multiple-input multiple-output (MIMO) system consists of multiple antennas at the receiver and transmitter. These multiple antennas can be used to improve the performance of the system through spatial diversity or increase the data rates by spatial multiplexing. One can also use some of the antennas for diversity and some for spatial multiplexing. The number used for diversity and spatial mul...

Space-time block coding (STBC) and Spatial multiplexing (SM) or BLAST (Bell Labs Layered Space-Time) are promise approaches that exploit the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work, we present a hybrid MIMO scheme that combines transmit diversity and spatial multiplexing. The proposed scheme can achieve arbitrary number of multi...

Multiple-input multiple-output (MIMO) communication systems use antenna arrays at both the transmitter and the receiver to offer substantial benefits in terms of rate and reliability. Two standard approaches for communicating in MIMO systems are spatial multiplexing and transmit diversity. Multiplexing sends independent information streams across the transmit antennas to maximize rate while tra...
