[en] We propose a new beamforming scheme for the
multi-user multiple-input-single-output (MISO) downlink channel.
While conventional beamforming aims at the minimization
of the transmit power subject to suppressing interference to
guarantee quality of service (QoS) constraints, here we exploit,
rather than suppress, the constructive part of interference. By
exploiting the power of constructively interfering symbols, the
proposed scheme achieves the required QoS at lower transmit
power. In addition, we derive an equivalent virtual multicast formulation
for the proposed optimization to facilitate the design of a
more efficient solver. Our simulation and analysis show significant
power savings for small scale MISO downlink channels with the
proposed optimization compared to conventional beamforming
optimization.
