Training Structure Design Optimization for Continuous Time-Varying Fading Channels
— In fast-varying faded channels the transmission can be organized into frames where the channel estimation is mainly training-based. For fast-varying fading channels the trainin...

Performance Analysis of Wireless Scheduling with ARQ in Fast Fading Channels
In this paper, we study the performance of opportunistic scheduling for downlink data transmissions with type-II packet-combining hybrid ARQ in a multirate cellular network for a f...

Modulation-adaptive cooperation in Rayleigh fading channels with imperfect CSI
Adaptive modulation can improve the throughput of cooperative communications, which has been shown in previous research. So far the adaptive modulation is applied with respect to ...

On the scaling laws of dense wireless sensor networks
We consider dense wireless sensor networks deployed to observe arbitrary random fields. The requirement is to reconstruct an estimate of the random field at a certain collector ...
