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)…

Carrier Frequency Offset Estimation for OCDM with Null Subchirps
Sidong Guo, Yiyin Wang, Xiaoli Ma
In this paper, we investigate the carrier frequency offset (CFO) identifiability problem in orthogonal chirp division multiplexing (OCDM) systems. We propose a transmission scheme…

Precheck Sequence Based False Base Station Detection During Handover: A Physical Layer Security Scheme
Xiangyu Li, Kaiwen Zheng, Sidong Guo +1
False Base Station (FBS) attack has been a severe security problem for the cellular network since 2G era. During handover, the user equipment (UE) periodically receives state infor…
