Abstract:We propose a new coding scheme for interference alignment in a single hop fast fading wireless network with general message demands. For the X Channel, the Degrees of Freedom (DoF) region achievable by the scheme is shown to touch a known outer bound at several points. For multiple multicast demands we show that the achievable region is at least half of the cut-set bound region. We also recover previous results of the K-user interference channel, X channel and the multicast channel. The key innovation in our scheme is the reduction of the vector space alignment problem to a combinatorial arrangement problem.
