Optimal Power Allocation over Parallel Gaussian Broadcast Channels
We consider the problem of optimal power allocation over a family of parallel Gaussian broadcast channels, each with a different set of noise powers for the users, and obtain a characterization of the optimal solution as well as the resulting capacity region. The solution has a simple greedy structure, just like the corresponding solution to the parallel Gaussian multi-access channel. It is a g...
متن کاملMultiple Access Gaussian Channels with Arbitrary Inputs: Optimal Precoding and Power Allocation
In this paper, we derive new closed-form expressions for the gradient of the mutual information with respect to arbitrary parameters of the two-user multiple access channel (MAC). The derived relations generalize the fundamental relation between the derivative of the mutual information and the minimum mean squared error (MMSE) to multiuser setups. We prove that the derivative of the mutual info...
متن کاملOptimal Power Allocation for Parallel Gaussian Broadcast Channels with Independent and Common Information
We consider a set of parallel, two-user Gaussian broadcast channels, where the transmitter wishes to send independent information to each of the receivers and common information to both receivers. The capacity region of this channel has been implicitly characterized in the past, but we provide an explicit characterization of the power and rate allocation schemes that achieve the boundary of the...
متن کاملOn Power Allocation for Parallel Gaussian Broadcast Channels with Common Information
This paper considers a broadcast system in which a single transmitter sends a common message and (independent) particular messages to K receivers over N unmatched parallel scalar Gaussian subchannels. For this system the set of all rate tuples that can be achieved via superposition coding and Gaussian signalling (SPCGS) can be parameterized by a set of power loads and partitions, and the bounda...
متن کاملPower Allocation for Discrete-Input Delay-Limited Fading Channels
We consider power allocation algorithms for fixed-rate transmission over Nakagami-m nonergodic block-fading channels with perfect transmitter and receiver channel state information and discrete input signal constellations, under both shortand long-term power constraints. Optimal power allocation schemes are shown to be direct applications of previous results in the literature. We show that the ...
