Abstract

Abstract:

Aiming at the problem of residual inter-relay interference (IRI) caused by the channel estimation error in amplify-and-forward two-path MIMO relay networks, a blind interference suppression scheme based on row space precoding under unknown channel state information (CSI) is proposed. In the new scheme, the desired received signal and IRI signal are mapped to an orthogonal subspace independent of CSI by alternating the row space precoding of the transmitted signal, so that the blind interference suppression of the IRI signal and relay noise under unknown channel state information is realized, and the optimal precoding design is given from the angle of the maximizing signal-to-noise ratio. Simulation results show that the proposed scheme can effectively avoid the impact of the link channel estimation error on the IRI suppression algorithm, and is superior to the traditional CSI-based interference suppression scheme in system performance and capacity.
