In this work, we present a two-hop OFDM MIMO relaying system with tensor codings at the source and the relay. The transmission scheme is composed of two steps. In the first one, the source sends a data tensor using a tensor space-time (TST) coding with multiplexing of the symbols across space (antennas), time (blocks) and frequency...

A multi-hop multi input multi output (MIMO) relay system with tensor coding at the source and relays is proposed in this paper. The tensor of signals received at destination satisfies a new tensor model, called high-order nested Tucker decomposition (HONTD), which generalizes an existing tensor decomposition. Exploiting this HONTD model allows...

Tensor models have been used extensively in signal processing applications to design different types of communication systems. This paper proposes, for the first time, the use of tensor models for optical communications. The signals of an optical dual-core coupler network are modeled as a multiway array (tensor), which satisfies a generalized...
