Optimized MSA DPD method for improving 5G multiband optical fronthaul performance
Microwave and Optical Technology Letters, Volume 65, Issue 12, Page 3326-3332, December 2023., 2023 Abstract A modified optimized magnitude‐selective affine (OMSA) model‐based digital predistortion (DPD) is presented that introduces the weighting function into our earlier proposed magnitude‐selective affine (MSA) method with an aim to further reduce the complexity overheads without affecting performance compared to the MSA method. This model utilizes

The Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023 This work proposes a low‐complexity digital backpropagation (DBP) implementation approach for high data rate optical transmission using a binary logarithmic step size method. The proposed scheme shows significant performance improvements over linear compensation and other DBP techniques in a 2400 km 112 Gbit/s DP‐16 QAM system, achieving a high ...

Fiber link design considerations for cloud-Radio Access Networks [PDF]
, 2014 Analog radio over fiber (RoF) links may offer advantages for cloud-Radio Access Networks in terms of component cost, but the behavior of the distortion with large numbers of subcarriers needs to be understood. In this paper, this is presented in terms of

An effective data communication community establishment scheme in opportunistic networks
IET Communications, Volume 17, Issue 12, Page 1354-1367, July 2023., 2023 We design an effective data communication community establishment scheme. By adding a data information flow attribute to each user, using the dynamic feedback adjustment mechanism and combining the entire communication community, the user's data information flow concentration is controlled at a relatively low level.
