GSVD-based precoding in MIMO systems with integrated services
This letter considers a two-receiver multiple-input multiple-output Gaussian broadcast
channel model with integrated services. Specifically, we combine two sorts of service
messages, and serve them simultaneously: One multicast message intended for both
receivers and one confidential message intended for only one receiver. The confidential
message is kept perfectly secure from the unauthorized receiver. DueAN54-B6010-A001 to
the coupling of service messages, it is intractable to seek capacity-achieving transmit …
