Scaling Analysis of Multilevel Polar Coded Modulation
IEEE Access, 2019 In this paper, we analyze and prove the capacity-achieving property of the equivalent asymmetric channels of multilevel polar-coded modulation in view of the scaling assuming regime, which employ some techniques of symmetric channels.

Joint source and turbo trellis coded hierarchical modulation for context-aware medical image transmission [PDF]
, 2013 An iterative Joint Source and Turbo Trellis Coded Hierarchical Modulation is introduced for robust context-aware medical image transmission. Lossless source compression as well as Quality of Service (QoS) might be considered as the main constraints in ...

A Note on the Dual Codes of Module Skew Codes [PDF]
, 2011 In [4], starting from an automorphism θ of a finite field ${\mathbb F}_q$ and a skew polynomial ring $R={\mathbb F}_q[X;\theta]$ , module θ -codes are defined as left R -submodules of R /Rf where f ∈R . In [4] it is conjectured that an Euclidean self-dual module θ -code is a θ -constacyclic code and a proof is given in the special ...
