BLIND SOURCE SEPARATION BASED ON SPACE-TIME-FREQUENCY DIVERSITY
BLIND SOURCE SEPARATION SPACE-TIME-FREQUENCY DIVERSITY
2015/9/29
We investigate the assumption that sources have disjoint support in the time domain, time-frequency domain, or frequency domain. We call such signals disjoint orthogonal. The class of signals that app...
SELF-AVERAGING FROM LATERAL DIVERSITY IN THE ITO-SCHRODINGER EQUATION
Random media Parabolic approximation Stochastic partial differential equations
2015/7/14
We consider the random Schrodinger equation as it arises in the paraxial regime for wave propagation in random media. In the white noise limit it becomes the Ito-Schrodinger stochastic partial differe...
Distribution of branch lengths and phylogenetic diversity under homogeneous speciation models
phylogenetic tree birth–death process Yule model branch length
2011/9/23
Abstract: The constant rate birth--death process is a popular null model for speciation and extinction. If one removes extinct and non-sampled lineages, this process induces `reconstructed trees' whic...
A Unified MGF-Based Capacity Analysis of Diversity Combiners over Generalized Fading Channels
Unified MGF-Based Capacity Analysis Diversity Combiners Generalized Fading Channels
2011/1/21
Unified exact average capacity results for L-branch coherent diversity receivers including equal-gain combining (EGC) and maximal-ratio combining (MRC) are not known. This paper develops a novel gener...

Diversity Spectra of Spatial Multipath Fading Processes
Diversity Spectra Spatial Multipath Fading Processes
2010/12/10
We analyse the spatial diversity of a multipath fading process for a finite region or curve in
the plane. By means of the Karhunen-Loève (KL) expansion, this diversity can be characterised
by the ei...
The densest local packings of N three-dimensional identical nonoverlapping spheres within a
radius Rmin(N) of a fixed central sphere of the same size are obtained for selected values of N up to N = 1...
Noncoherent Interference Alignment: Trade Signal Power for Diversity Towards Multiplexing
Noncoherent Interference Alignment Trade Signal Power Diversity Multiplexing
2010/12/13
This paper proposes the first known universal interference alignment scheme for general (1 × 1)K interference networks, either Gaussian or deterministic, with only 2 symbol extension.
Open-Loop Spatial Multiplexing and Diversity Communications in Ad Hoc Networks
Open-Loop Spatial Multiplexing Diversity Communications Ad Hoc Networks
2010/12/7
This paper investigates the performance of open-loop multi-antenna point-to-point links in ad
hoc networks with slotted ALOHA medium access control (MAC). We consider spatial multiplexing
transmissi...
Finite-SNR Diversity-Multiplexing Tradeoff via Asymptotic Analysis of Large MIMO Systems
Diversity-multiplexing tradeoff outage probability
2010/12/9
Diversity–multiplexing tradeoff (DMT) was characterized asymptotically (SNR-> infinity) for i.i.d. Rayleigh fading channel by Zheng and Tse [1].
Diversity and Arbitrage in a Regulatory Breakup Model
Diversity Arbitrage Regulatory Breakup Model
2010/4/27
In 1999 Robert Fernholz observed an inconsistency between the normative assumption of existence of an equivalent martingale measure (EMM) and the empirical reality of diversity in equity markets. We e...
