—We consider the problem of network coding across three unicast sessions over a directed acyclic graph, when each session has min-cut one. Previous work by Das et al. adapted a precoding-based interference alignment technique, originally developed for the wireless interference channel, specifically to this problem. We refer to this approach as… (More)

—We consider the problem of network coding across three unicast sessions over a directed acyclic graph, where each sender and the receiver is connected to the network via a single edge of unit capacity. We adapt a precoding-based interference alignment technique, originally developed for the wireless interference channel, to find a solution to this… (More)

—We consider the interference channel with K transmitters and K receivers all having a single antenna, wherein the K × K transfer matrix representing this channel has rank D (D < K). The degrees of freedom (DoF) of such channels are not known as the rank deficiency in the transfer matrix creates algebraic dependencies between the channel coefficients. We… (More)
