Locally Orthogonal Training Design in Cloud-RANs
2016 IEEE Global Communications Conference (GLOBECOM), 2016We consider training-based channel estimation for cloud radio access networks (CRANs), in which a large amount of remote radio heads (RRHs) and users are randomly scattered over a certain service area. In this model, assigning orthogonal training sequences to all users, if possible, will cause a substantial overhead to the overall network.

Cloud-RAN Modeling Based on Parallel Processing
IEEE Journal on Selected Areas in Communications, 2018We consider in this paper the implementation of a cloud radio access network (C-RAN) on a centralized multi-core system supporting the base band processing of several distributed antennas. We present a parallel processing model based on both functional and data decomposition of virtualized base band unit (BBU) functions in order to reduce their runtime.

Deterministic Scheduling of Periodic Messages for Cloud RAN
2018 25th International Conference on Telecommunications (ICT), 2018A recent trend in mobile networks is to centralize in distant data-centers the processing units which were attached to antennas until now. The main challenge is to guarantee that the latency of the periodic messages sent from the antennas to their processing units and back, fulfills protocol time constraints.

Evaluation Methodology for Fast Switching Cloud RAN Systems
IEEE Communications Letters, 2017The switching scheme between base band units (BBUs) and remote radio heads (RRHs) is a key point in a cloud radio access network (C-RAN). Fast BBU-RRH switching schemes will play crucial roles in future flexible C-RAN systems. In this letter, an evaluation model is proposed to analyze the performance of fast switching schemes.
