We consider a broadcast channel, in which a multi-antenna transmitter (Alice) sends K confidential information signals to K legitimate users (Bobs) in the presence of L passive eavesdroppers. Alice uses MIMO precoding to generate the information signals along with its own (Tx-based) friendly jamming. Interference at each Bob is removed by MIMO zero-forcing.(More)
—This paper considers a broadcast channel with a multi-antenna transmitter (Alice) sending two independent confidential data streams to two legitimate users (Bob and Charlie) in the presence of a passive eavesdropper (Eve). To enhance their secrecy rates, Bob and Charlie are assumed to be capable of self-interference suppression (SIS). Alice, on the other(More)
