Query: Quality-Driven Resource Allocation for Full-Duplex Delay-Constrained
  Wireless Video Transmissions   In this paper, wireless video transmission over full-duplex channels under
total bandwidth and minimum required quality constraints is studied. In order
to provide the desired performance levels to the end-users in real-time video
transmissions, quality of service (QoS) requirements such as statistical delay
constraints are also considered. Effective capacity (EC) is used as the
throughput metric in the presence of such statistical delay constraints since
deterministic delay bounds are difficult to guarantee due to the time-varying
nature of wireless fading channels. A communication scenario with multiple
pairs of users in which different users have different delay requirements is
addressed. Following characterizations from the rate-distortion (R-D) theory, a
logarithmic model of the quality-rate relation is used for predicting the
quality of the reconstructed video in terms of the peak signal-to-noise ratio
(PSNR) at the receiver side. Since the optimization problem is not concave or
convex, the optimal bandwidth and power allocation policies that maximize the
weighted sum video quality subject to total bandwidth, maximum transmission
power level and minimum required quality constraints are derived by using
monotonic optimization (MO) theory.
