In this paper, Slepian-Bangs-type formulas for Complex Elliptically Symmetric distributed (CES) data vectors in the presence of model misspecification are provided. The basic Slepian-Bangs (SB) formula has been introduced in the array processing literature as a convenient and compact representation of the Fisher Information Matrix (FIM) for parameter estimation under (parametric) Gaussian data ...

We consider the multiple access source coding (MASC) problem (also known as the SlepianWolf problem) for situations where the joint source statistics are unknown a priori. Since neither encoder receives information about the joint source statistics, we allow an asymptotically negligible amount of communication between the encoders. We prove the existence of universal 2-encoder Linked MASCs (LMA...

Relays are being deployed in both fourth generation cellular systems and wide metropolitan area networks in order to increase coverage and spectral efficiency. In this article, we consider a network with three half-duplex relays assisting the transmission from a source towards a destination. By assuming that transmission time consists of a sequence of phases, we develop a transmission scheme in...

Distributed Arithmetic Coding (DAC) is an effective implementation of Slepian-Wolf coding, especially for short data blocks. To research its properties, the concept of DAC codeword distribution along proper and wrong decoding paths has been introduced. For DAC codeword distribution of equiprobable binary sources along proper decoding paths, the problem was formatted as solving a system of funct...

We present a unified approach for constructing Slepian functions — also known as prolate spheroidal wave on the sphere arbitrary tensor ranks including scalar, vectorial, and rank 2 tensorial functions, using spin-weighted spherical harmonics. For special case of cap regions, we derived commuting operators, allowing numerically stable computationally efficient construction spherical-harmonic-ba...
