Achievable rate region based on coset codes for multiple access channel with states
We derive a new achievable rate region for the problem of communicating over a multiple access channel with states. Our coding technique is based on the ensemble of nested coset codes and the technique of typicality decoding. Exploiting structure in this ensemble, we analyze a more efficient decoding strategy to improve upon the rate region achievable using unstructured codes. We identify examp...
متن کاملAn Achievable Rate-Distortion Region for Multiple Descriptions Source Coding Based on Coset Codes
We consider the problem of multiple descriptions (MD) source coding and propose new coding strategies involving both unstructured and structured coding layers. Previously, the most general achievable rate-distortion (RD) region for the l-descriptions problem was the Combinatorial Message Sharing with Binning (CMSB) region. The CMSB scheme utilizes unstructured quantizers and unstructured binnin...
متن کاملAn Achievable Rate Region for Cooperative Multiple Access Channel
An achievable rate region for a 3-node cooperative multiple access channel (CMAC) is presented in this paper. A CMAC contains multiple users cooperatively transmitting information to a single destination node. It includes the traditional multiple access channel that assumes no communication between source nodes, and multiple input single output (MISO) system that contains ideal links between so...
متن کاملAn Achievable Rate Region for Relay Multiple Access Channel Based on Decode-and-Forward
In this paper, we model a specific relay channel named relay multiple access channel (RMAC) aiming at providing a clue to select the relay node in multiple access channels such as the uplink of cellular communication system. In this channel, the relay node not only aids to send the information of the source but also sends its private message to the destination. We derive the achievable rate reg...
متن کاملAn achievable rate region for the multiple-access channel with feedback
An achievable rate region R , G I( X, ; Y 1 X,, U), R 2 G 1(X2; YIX,, U), RI + R2 G 4x1, X2; Y), where P(U, xl, XZ, Y) = p(u)p(x,~u)p(x~~u)p(ylxl,x~), is established for the multiple-access channel with feedback. Time sharing of these achievable rates yields the rate region of this paper. This region generally exceeds the achievable rate region without feedback and exceeds the rate point found ...
