Recursive Stream Selection for Sum-Rate Maximization on the Interference Channel
Résumé
This paper presents a successive stream selection algorithm
than can be used for the interference channel.
The proposed solution is a stream-wise construction of
the precoding and decoding vector sets. These beams
are selected to minimize the interference between the
selected streams based on the projections of the nominal
directions derived via SVD. The projections are made
such that the obtained new stream is in both null spaces
of the receiving and transmitting directions of all previously
selected streams. This means that it interferes the
least with the other selected streams and is also weakly
interfered by them.
