The capacity of a class of broadcast channels
نویسنده
چکیده
T HE discrete memoryless broadcast channel (%P(YJlX), 94 x 3) consists of three finite sets % ., 9, % and a probability transition matrixp(y,zjx). Let p,(ylx) andp,(zIx) be the two marginals of p(y,zlx), and let P, and P2 denote the discrete memoryless channels with probability transition matrices p&y Ix) and pz(zlx), respectively. Recall the following three relations between P, and P2. Definition 1: Channel P2 is said to be a degraded form of P, if there exists a probability transition matrixPs(zIY) such that

متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...

متن کاملTwo Classes of Broadcast Channels With Side-Information: Capacity Outer Bounds
In this paper, we derive outer bounds on the capacity region of two classes of the general two-user discrete memoryless broadcast channels with side-information at the transmitter. The first class comprises the classical broadcast channel where a sender transmits two independent messages to two receivers. A constraint that each message must be kept confidential from the unintended receiver cons...
متن کاملThe capacity of a class of 3-receiver broadcast channels with degraded message sets
Körner and Marton established the capacity region for the 2-receiver broadcast channel with degraded message sets. Recent results and conjectures suggest that a straightforward extension of the Körner-Marton region to more than 2 receivers is optimal. This paper shows that this is not the case. We establish the capacity region for a class of 3-receiver broadcast channels with 2 degraded message...
متن کاملVideo communication over broadcast channels
This paper investigates the problem of communicating video over a broadcast channel. The broadcast channel is expressed in terms of the channel capacity that exists between the transmitter and each receiver in the broadcast area { Shannon's separation theorem does not apply for video communication over this class of channels. Digital (discrete time, discrete amplitude) and hybrid (discrete time...
