- Abstract
- This paper investigates the resolution enhancement of correlated OTDR using Eigen-decomposition based algorithm. The algorithm separates the space spanned by the measured data into what are called noise and signal subspace and then pseudo-spectrum is calculated by using signal steering vector and noise subspace matrix. Attenuation dead zone of the correlated OTDR is improved up to 45 % by the Eigen-decomposition based algorithm.
