On multicast interference alignment in multihop systems

This paper investigates alignment schemes for multicast traffic over an equal path length multihop time-varying circularly symmetric fading channels. A finite field channel model is assumed, where the inputs and channel gains belong to the same field F
_q
. The mechanism used in this paper combines elements of the alignment strategy developed by Nazer et al. with the multihop unicast alignment strategy devised by Jeon et al..
