A maximum entropy approach to OFDM channel estimation
In this work, a Bayesian framework for OFDM channel estimation is proposed. Using the maximum entropy principle to exploit prior system information at the receiver, we successively...

Spatially Interpolated OFDM with Channel Estimation for Fast Fading Channels
— OFDM is well suited for data-transmission over frequency-selective channels. If the cyclic prefix is chosen sufficiently long, intersymbol interference is avoided. Thus, the ...

QoS-Driven Power Allocation Over Parallel Fading Channels With Imperfect Channel Estimations in Wireless Networks
— We propose the quality-of-service (QoS) driven power allocation schemes for parallel fading channels when considering imperfect channel estimations. In particular, the parallel...

Modeling Node Compromise Spread in Wireless Sensor Networks Using Epidemic Theory
Motivated by recent surfacing viruses that can spread over the air interfaces, in this paper, we investigate the potential disastrous threat of node compromise spreading in wirele...
