A 3-node lossy source coding problem for a 2-DMS(X1, X2) is considered. Source nodes 1 and 2 observe X1 and X2, respectively, and each wishes to reconstruct the other source with a prescribed distorti...
A new statistical model for routing of gate arrays is described. The model takes into consideration the effect of gate utilization on wiring area requirement. Model computed wiring area estimates sugg...
A relay channel consists of an input x,, a relay output yl, a cJmnnel output y, and a relay sender x2 (whose trasmission is allowed to depend on the past symbols y,). l%e dependence of the received sy...
On Adaptive Transmission for Energy Efficiency in Wireless Data Networks
Adaptive transmission broadcast energy-efficient transmission iterative algorithm multiple-access power control scheduling time-division wireless networks
2015/8/12
This paper investigates the problem of energy-efficient transmission of data packets in a wireless network by jointly adapting to backlog and channel condition. Specifically, we consider minimum-energ...
A Proof of Marton’ s Coding Theorem for the Discrete Memoryless Broadcast Channel
Marton’ s Coding Theorem Discrete Memoryless Broadcast Channel
2015/8/12
A simple proof using random partitions and typicality is given for Marton’ s coding theorem for broadcast channels.
The Capacity of the Physically Degraded Gaussian Broadcast Channel with Feedback
Physically Degraded Gaussian Broadcast Channel Feedback
2015/8/12
Bounds on the output entropy of the additive white Gaussian noise (AWGN) channel with feedback are used to prove that the capacity of the degraded additive white Gaussian noise (DAWGN) broadcast chann...
An Outer Bound to the Capacity Region of the Broadcast Channel
Outer Bound Capacity Region Broadcast Channel
2015/8/12
An outer bound to the capacity region of the two-receiver discrete memoryless broadcast channel is given. The outer bound is tight for all cases where the capacity region is known. When specialized to...
The Capacity Region of a Class of 3-Receiver Broadcast Channels with Degraded Message Sets
Capacity Region 3-Receiver Broadcast Channels Degraded Message Sets
2015/8/12
Korner 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 Korner-...
Broadcasting Data from an SBAS Reference Network over Low Rate Broadcast Channels
Broadcasting Data SBAS Network over Low Rate Broadcast Channels
2015/6/29
Space Based Augmentation Systems (SBAS) have been developed principally to augment GPS for aviation and other safety of life applications. An SBAS reference network generates corrections and integrity...
The Advantages of Local Monitoring and VHF Data Broadcast for SBAS
Local Monitoring VHF Data Broadcast SBAS
2015/6/26
In Space Based Augmentation Systems (SBAS), many reference receivers are placed throughout a large region, and their measurements are combined to create a set of corrections for each ranging satellite...
