One-Bit Quantization and Distributed Detection with an Unknown Scale Parameter [PDF]

open access: yesAlgorithms, 2015
We examine a distributed detection problem in a wireless sensor network, where sensor nodes collaborate to detect a Gaussian signal with an unknown change of power, i.e., a scale parameter.
