A Finite Block Length Achievability Bound for Low Probability of Detection Communication
Nick Letzepis
Low probability of detection (or covert) communication refers to the scenario where information must be sent reliably to a receiver, but with low probability of detection by an adv…
Causal/Predictive Imperfect Channel State Information in Block-Fading Channels
Khoa D. Nguyen, Nick Letzepis, Albert Guillen i Fabregas +1
We consider a multi-input multi-output (MIMO) block-fading channel with a general model for channel state information at the transmitter (CSIT). The model covers systems with causa…
Multipath Parameter Estimation from OFDM Signals in Mobile Channels
Nick Letzepis, Alex Grant, Paul Alexander +1
We study multipath parameter estimation from orthogonal frequency division multiplex signals transmitted over doubly dispersive mobile radio channels. We are interested in cases wh…
MIMO ARQ with Multi-bit Feedback: Outage Analysis
Khoa D. Nguyen, Lars K. Rasmussen, Albert Guillen i Fabregas +1
We study the asymptotic outage performance of incremental redundancy automatic repeat request (INR-ARQ) transmission over the multiple-input multiple-output (MIMO) block-fading cha…
Outage Probability of the Gaussian MIMO Free-Space Optical Channel with PPM
Nick Letzepis, Albert Guillen i Fabregas
The free-space optical channel has the potential to facilitate inexpensive, wireless communication with fiber-like bandwidth under short deployment timelines. However, atmospheric…
