In this paper, we obtain a general achievable rate region and some certain capacity theorems for multiple-access relay channel (MARC), using decode and forward (DAF) strategy at the relay, superposition coding at the transmitters. Our general rate region (i) generalizes the achievability part of Slepian-Wolf multiple-access capacity theorem to the MARC, (ii) extends the Cover-El Gamal best achi...

other areas. However, the spectral properties of the Laplace transform tend to complicate its numerical treatment; therefore, the closely related “truncated” Laplace transforms are often used in applications. In this dissertation, we construct efficient algorithms for the evaluation of the singular value decomposition (SVD) of such operators. The approach of this dissertation is somewhat simila...

An efficient hybrid distributed video coding (HDVC) scheme combining residual coding, SW-SPIHT coding and intra-mode decision technology is proposed to offer good rate-distortion performance and low-complexity encoding. The scheme adopts the waveletdomain Wyner-Ziv codec to compress the residual frame between the current frame and its reference frame. An intra-mode decision based on the tempora...

The purpose of the work reported here is two-fold. First, it extends the earlier results to finite transforms. Results are derived for the finite forms of both the harmonic oscillator and prolate spheroidal equations. Two—dimensional forms of the problems are considered. These results are the natural finite analogues of those presented by both Gabor and Slepian. By treating both problems togeth...
