To reduce active relays in peer-to-peer relay networks, a sparsity promoting penalty term is introduced into the objective function to obtain beamforming weights through minimization of the total relay transmit power while the signal-to-interference-plus-noise ratio (SINR) at the destinations are guaranteed to be above certain thresholds. To deal with the non-convexity of the problem, we use semidefinite relaxation to turn this problem into a semidefinite programming (SDP) problem. Then we candoi:10.2991/icmmita-15.2015.77 fatcat:u6kxeu3zufe27cxi5z4gl3b75a
