Vector Orthogonal Chirp Division Multiplexing Over Doubly Selective Channels
Deyu Lu, Xiaoli Ma, Yiyin Wang
In this letter, we extend orthogonal chirp division multiplexing (OCDM) to vector OCDM (VOCDM) to provide more design freedom to deal with doubly selective channels. The VOCDM modu…

Designing Affine OCDM Systems with Maximum Diversity
Sidong Guo, Xiaoli Ma, Yiyin Wang
This work considers the problem of enabling maximum multipath diversity of orthogonal chirp division multiplexing (OCDM)-based systems. We define and study an Affine OCDM (A-OCDM)…
