Multi-device selection scheduling in non-identically distributed fading channels
Multiuser selection scheduling concept has been recently proposed in the literature in order to increase the multiuser diversity gain and overcome the significant feedback requirements for the opportunistic scheduling schemes. The main idea is that reducing the feedback overhead saves per-user power that could potentially be added for the data transmission. In this work, we propose to integrate...
متن کاملTranslation vectors with non-identically distributed components
A model for non-Gaussian random vectors is presented that relies on a modification of the standard translation transformation which has previously been used to model stationary non-Gaussian processes and non-Gaussian random vectors with identically distributed components. The translation model has the ability to exactly match target marginal distributions and a broad variety of correlation matr...
متن کاملRate-Compatible Polar Codes for Wireless Channels
A design of rate-compatible polar codes suitable for HARQ communications is proposed in this paper. An important feature of the proposed design is that the puncturing order is chosen with low complexity on a base code of short length, which is then further polarized to the desired length. A practical ratematching system that has the flexibility to choose any desired rate through puncturing or r...
متن کاملPolar codes for distributed hierarchical source coding
Hierarchical source coding, also known as successive refinement of information, was introduced by Koshelev [1,2] and Equitz and Cover [3]. This problem is concerned with the construction of a source code for a discrete memoryless source X with respect to a given distortion measure d1 that can be further refined to represent the same source within another distortion measure d2 so that both repre...
متن کاملHybrid Regenerating Codes for Distributed Storage Systems
Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...
