Time-Varying Channel Estimation Based on Distributed Compressed Sensing for OFDM Systems [PDF]

open access: yesSensors
For orthogonal frequency division multiplexing (OFDM) systems in high-mobility scenarios, the estimation of time-varying multipath channels not only has a large error, which affects system performance, but also requires plenty of pilots, resulting in low

A Compressed Sampling and Dictionary Learning Framework for WDM-Based Distributed Fiber Sensing [PDF]

open access: green, 2017
We propose a compressed sampling and dictionary learning framework for fiber-optic sensing using wavelength-tunable lasers. A redundant dictionary is generated from a model for the reflected sensor signal. Imperfect prior knowledge is considered in terms
