Broadcast Channels With Privacy Leakage Constraints

Capacity of Fading Broadcast Channels with Rate Constraints

For fading broadcast channels, different capacity regions such as the ergodic, outage, minimum rate, or limited-jitter capacity region can be represented by a triplet of rate constraint parameters from each user: a maximum rate, a minimum rate, and a shortage probability over which the minimum rate needs not be guaranteed. For each fading state, the capacity region is obtained by evaluating a f...

Broadcast channels with confidential messages

Absrfucr-Given two discrete memoryless channels @MC’s) with a common input, it is desired to transmit private messagea to receiver 1 at r&R, andcommon meswgea to both receivers at rate R,, while keeping receiver 2 as ignorant of tbe private messages as possible. Measurhg ignorance by equivocation, a single-letter characterization is given of the. achievable trfplea (RI&R,-,) where 4 is the equi...

Broadcast channels

We introduce the problem of a single source attempting to communicate information simultaneously to several receivers. The intent is to model the situation of a broadcaster with multiple receivers or a lecturer with many listeners. Thus several different channels with a common input alphabet are specified. We shall determine the families of simultaneously achievable transmission rates for many ...

Capacity Regions for Broadcast Channels With Degraded Message Sets and Message Cognition Under Different Secrecy Constraints

This paper considers a three-receiver broadcast channel with degraded message sets and message cognition. The model consists of a common message for all three receivers, a private common message for only two receivers and two additional private messages for these two receivers, such that each receiver is only interested in one message, while being fully cognizant of the other one. First, this m...
