Interference channel sum rate optimization on the Grassmann manifold
M Rezaee, M Guillaud - 2012 International Symposium on …, 2012 - ieeexplore.ieee.org
The problem of truncated unitary precoder design for the Multiple-Input Multiple-Output
Interference Channel (MIMO-IC) is investigated. A simple gradient ascent method is utilized
over the Grassmann manifold to maximize the sum rate achieved over the MIMO-IC. Since
such optimization methods are not guaranteed to converge to the global solution, we also
introduce an implementation of simulated annealing for the problem at hand and compare
the performance of the two methods. The results show that the gradient on the Grassmann …
