On the capacity of multisource non-coherent network coding

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani, Soheil Mohajerzefreh

We consider multisource non-coherent network coding, where multiple sources send information to one or multiple receivers. We prove that this is equivalent to a ldquosubspacerdquo channel, that takes subspaces as inputs and outputs. We then show that the r ...

A Deterministic Approach to Wireless Network Error Correction

Suhas Diggavi, Soheil Mohajerzefreh

In this paper we consider communication between two special nodes ("source" and "destination") in a wireless relay network, which has malfunctioning or malicious nodes (inserting errors). We develop the model for wireless network communication in the prese ...

Transmission techniques for relay-interference networks

Christina Fragouli, Suhas Diggavi, Soheil Mohajerzefreh

In this paper we study the relay-interference wireless network, in which relay (helper) nodes are to facilitate competing information ﬂows over a wireless network. We examine this in the context of a deterministic wireless interaction model, which eliminat ...

Asymmetric multi-level diversity coding

Suhas Diggavi, Soheil Mohajerzefreh

Symmetric multilevel diversity coding was introduced by Roche et al, where a set of K information sources is encoded by K encoders and the decoders reconstruct sources 1, . . . , k, where k is the number of encoders to which they have access. In this paper ...
