Abstract
This paper considers throughput maximization in relays based multi-user wireless networks by enhancing the worst signal-to-interference-plus-noise ratio (SINR) among multiple users. Unlike the existing approaches that use semidefinite relaxation coupled with Gaussian randomization (SDR-G), we utilize the d.c. (difference of two convex functions) structure of the resulting objective function to develop efficient iterative algorithms of low complexity. Numerical results demonstrate that the proposed algorithm locates solutions that are close to the upper bound by a few iterations, and hence, shows better performance than the other methods.
