Robust SINR-constrained MISO downlink beamforming: When is semidefinite programming relaxation tight?

12 years 10 months ago

We consider the robust beamforming problem under imperfect channel state information (CSI) subject to SINR constraints in a downlink multiuser MISO system. One popular approach to...
