An extended interior-point method for transmit beamforming in multi-group multicasting

We address the problem of transmit beamforming to multiple cochannel multicast groups where the total transmitted power is minimized subject to quality-of-service (QoS) constraints at the receivers. The iterative second-order cone programming (SOCP) approach recently proposed in [2] is a powerful to...
