Index coding with side information
The Index Coding problem has attracted a considerable amount of attention in the recent years. The problem is motivated by several applications in wireless networking and distributed computing. An instance of the index coding problem includes a sender that holds an input x = (x1, x2, . . . , xn) ∈ {0, 1} and communicates with n receivers R1, . . . , Rn using wireless broadcast channel. Each rec...
متن کاملSecure Index Coding with Side Information
Security aspects of the Index Coding with Side Information (ICSI) problem are investigated. Building on the results of Bar-Yossef et al. (2006), the properties of linear coding schemes for the ICSI problem are further explored. The notion of weak security, considered by Bhattad and Narayanan (2005) in the context of network coding, is generalized to block security. It is shown that the coding s...
متن کاملEfficient Pattern Index Coding Using Syndrome Coding and Side Information
Pattern-based video coding focusing on moving regions has already established its superiority over the H.264 at very low bit rate. Up to a certain limit, the larger the number of pattern templates, the better the approximation to the moving regions. However, beyond that limit no coding gain is observed due to the need of an excessive number of pattern identification bits (PIC). Recently, distri...
متن کاملOn Coding with Rate-Limited Side Information
We consider an i.i.d. state-dependent channel with partial (rate limited) channel state information (CSI) at the transmitter (CSIT) and full CSI at the receiver (CSIR). The CSIT comprises a non-causal rate limited part, which is communicated by a third party (a genie) over a way-side channel, and may also include outputs of a deterministic scalar quantizer of the state. A single letter expressi...
متن کاملSource Coding with Decoder Side Information
In this report, we study source coding problems with decoder side information (SI). Source coding problems with decoder side information are a special case of distributed source coding problems. We outline the relation between various distributed source coding problems in Table 1 with the help of Figure 1. For reference, we also include the standard single-source lossless and lossy compression ...
