Research on Performance of Cooperative FSO Communication System Based on Hierarchical Modulation and Physical Layer Network Code

Autor: Huaijun Qin, Yang Cao, Xiaofeng Peng, Zupeng Zhang

Publikováno v: Sensors, Vol 22, Iss 18, p 6912 (2022)

To solve the problem that the channel conditions in asymmetric cooperative FSO communication systems are not fully utilized, and the data reliability deteriorates due to high-order modulation, we proposed a layered modulation, joint physical-layer ne

Research of Phase Compensation Methods Based on the Median Reweighted Wirtinger Flow Algorithm

Autor: Yang Cao, Zupeng Zhang, Xiaofeng Peng, Huaijun Qin, Wenqing Li

Publikováno v: Photonics, Vol 9, Iss 9, p 619 (2022)

An improved non-convex optimized phase recovery algorithm is used to compensate for wavefront aberrations caused by atmospheric turbulence and pointing errors in the vortex beam. The algorithm is divided into two parts: initialization and iteration.

Research on Polarization Coding Cooperative Communication Scheme for FSO System

Autor: Yang Cao, Huaijun Qin, Xiaofeng Peng, Yuhan Wang, Zupeng Zhang

Publikováno v: Electronics; Volume 11; Issue 10; Pages: 1597

To solve the problems of interruption events and the high bit-error rate of the FSO system caused by atmospheric turbulence, an FSO cooperative communication scheme based on system polarization code is proposed. In this scheme, the upper limit of the
