Gaussian approximation of the LLR distribution for the ML and partial marginalization MIMO detectors
We derive a Gaussian approximation of the LLR distribution conditioned on the transmitted signal and the channel matrix for the soft-output via partial marginalization MIMO detect...

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