Optimizing the Transmit Power for Slow Fading Channels
by Paschalis Ligdas, Nariman Farvardin — 2000 — IEEE Transactions on Information Theory
…We consider the design of power-adaptive systems for minimizing the average bit-error-rate over flat fading channels. Channel state information, obtained through estimation at the receiver, is sent to the transmitter over a feedback channel, where it is used to optimally adapt the transmit power. We…

Adaptive Rate Allocation In A Joint Source/channel Coding Framework For Wireless Channels
by Hamid Jafarkhani, Paschalis Ligdas, Nariman Farvardin — 1996 — in Proc. IEEE Vehicular Technology Conference, Atlanta, GA
…We propose an adaptive rate allocation scheme to choose the rates of the source coder and channel coder pair optimally. We express the end-to-end expected distortion in terms of the source coder distortion and the channel distortion. Also, we propose a modified Gilbert noise channel to model the com…
