We consider adaptive downlink beamforming strategy for multiuser Multi-Input Single-Output(MISO) systems. It is well known that the non-linear dirty paper coding (DPC) can entirely eliminate the interference of the other users, but it is computationally prohibitive. The Zero-Forcing Beamforming (ZFBF) is an alternative solution also with high complexity due to the inversion of composite channel matrix...
