Abstract: Orthogonal chirp division multiplexing (OCDM) is a new multi-carrier scheme based on chirp spread spectrum (CSS) recently introduced and shown to be more robust to interference. In this ...

Abstract: Phase fading is a critical issue that hinders phase retrieval in the phase-sensitive optical time-domain reflectometry (ϕ-OTDR). This paper introduces a novel approach for mitigating fading ...
