We derive the capacity region for a broadcast channel with intersymbol interference (ISI) and colored Gaussian noise under an input power constraint. The region is obtained by first defining a similar channel model, the circular broadcast channel, which can be decomposed into a set of parallel degraded broadcast channels. The capacity region for parallel degraded broadcast channels is known. We...

In this paper, we first consider a channel that is contaminated by two independent Gaussian noises S ∼ N (0, Q) and Z0 ∼ N (0, N0). The capacity of this channel is computed when independent noisy versions of S are known to the transmitter and/or receiver. It is shown that the channel capacity is greater then the capacity when S is completely unknown, but is less then the capacity when S is perf...

In noncooperative networks, resources are shared among selfish users, which optimize their individual performance measure. We consider the generic and practically important case of atomic resource sharing, in which traffic bifurcation is not implemented, hence each user allocates its whole traffic to one of the network resources. We analyze topologies of parallel resources within a game-theoret...

The bronchodilator response after four different modes of inhalation of 0.25 mg terbutaline from a Turbuhaler was assessed, in a double-blind cross-over study, of 14 asthmatic children aged 8-14 yrs (mean 11.6 yrs). The children inhaled as fast as possible (mean peak inspiratory flow rate = 53 l.min-1), because fast inhalations have been found to be more efficient than slow inhalations when the...

In multiuser wireless systems, dynamic resource allocation between users and over time significantly improves efficiency and performance. In this two-part paper, we study three types of capacity regions for fading broadcast channels and obtain their corresponding optimal resource allocation strategies: the ergodic (Shannon) capacity region, the zero-outage capacity region, and the outage capaci...
