In energy harvesting (EH) wireless communications, full channel state information (CSI) at transmitter (TX) is generally needed to determine transmission power. In this paper, we propose a transmission power policy based on only 1-bit feedback of the CSI sent from the receiver (RX), for an EH communication system over Rayleigh fading channels. The RX periodically sends 1-bit feedback by comparing...
In this paper, we consider many problems in Bayesian inference — from drawing samples to posteriors, to calculating confidence intervals, to implementing posterior matching algorithms, by finding maps that push one distribution to another. We show that for a large class of problems (with log-concave likelihoods and log-concave priors), these problems can be efficiently solved using convex optimization...
Transmissions over hybrid wireline-wireless networks suffer both packet losses and bit errors. To facilitate delay-sensitive audio/video communications over hybrid networks, low-delay error recovery techniques, such as forward error correction (FEC) and multiple description coding (MDC), are utilized to provide protection against bit errors and packet losses, respectively. As a means of joint source-channel...
