On the capacity for distributed index coding [PDF]
The distributed index coding problem is studied, whereby multiple messages are stored at different servers to be broadcast to receivers with side information. First, the existing composite coding scheme is enhanced for the centralized (single-server) index coding problem, which is then merged with fractional partitioning of servers to yield a new ...

An equivalence between network coding and index coding [PDF]
We show that the network coding and index coding problems are equivalent. This equivalence holds in the general setting which includes linear and non-linear codes. Specifically, we present an efficient reduction that maps a network coding instance to an index coding one while preserving feasibility.

Index coding via random coding [PDF]
The index coding problem is a simple dis- tributed source coding problem in which a sender broad- casts multiple messages to their respective receivers with side information about other messages. This problem arises in many applications such as content broadcasting, dis- tributed caching, and wireless interference management.

Optimal Linear Error Correcting Delivery Schemes for Two Optimal Coded Caching Schemes
For coded caching problems with small buffer sizes and the number of users no less than the amount of files in the server, an optimal delivery scheme was proposed by Chen, Fan, and Letaief in 2016. This scheme is referred to as the CFL scheme.

On the Optimality of Linear Index Coding Over the Fields With Characteristic Three
It has been known that the insufficiency of linear coding in achieving the optimal rate of the general index coding problem is rooted in its rate’s dependency on the field size. However, this dependency has been described only through the two well-

Protection scheme of subcarrier index in OFDM with index modulation aided by LDPC coding
The receiver of OFDM with Index Modulation (OFDM-IM) usually adopts a Log Likelihood Ratio (LLR) detection algorithm based on the activation state of subcarriers.

An Efficient Application of Turbo Coding for OFDM In-Phase/Quadrature Index Modulation
We present a method to efficiently apply turbo coding to OFDM in-phase/quadrature index modulation (OFDM-IQ-IM) for both cases of presence and absence of puncturing.
