The sum capacity of a non-degraded Gaussian broadcast channel with multiple antennas at the transmitter and receivers is characterized under a certain condition. The sum capacity is achieved using a precoding technique for channels with transmitter side information. The optimal precoder has the structure of a decision-feedback equalizer.
