Abstract

This paper proposes a dual-mode chirp spread spectrum (CSS) modulation that uses time-domain multiplexing to simultaneously carry information across two modes. The construction increases data rate over conventional CSS while retaining the robustness benefits of chirp signaling, making it well suited for vehicular and LPWAN deployments.
