Present mobile communication system suffers from the exponentially increased mobile traffic and research on the fifth generation (5G) mobile network architectures is ongoing to solve this problem. We investigate the feasibility of the proposals used for the network architecture evolution from 4G to 5G and first propose a compatible network architecture, which decouples the management plane, the control...
Cloud radio access network (C-RAN) centralizes several baseband units to form a pool, which is the primary form of the wireless network virtualization. Some aspects of C-RAN are always developing, such as the processing capacity and multiple radio access technology (multi-RAT) convergence. In this paper, the Not Only Stack (NO Stack) framework, as a virtualization approach, is suggested to be employed...
Existing mobile networks suffer from complex protocols, inflexible equipment, and vendor specific configuration interfaces and other problems. This paper proposes a novel framework, NO Stack (short for “Not Only Stack”), which is a software-defined framework for 5G mobile network. NO Stack emphasizes on the decoupling of the user plane, control plane and management plane, pushes down the layer-by-layer...
SERCOS-III is the international standard on the third generation serial communication protocol for real-time data communication among the controller and actuators with the advantage of openness, compatibility, high speed, and reliability. Based on studying on the SERCOS-III protocol and ARM embedded control technology, presents one kind of SERCOS-III high speed communication system and discusses the...
The cognitive radio technology is very helpful in improving the use of spectrum resources and reacting its operating environment. This paper presents a novel embedded framework for secondary user based a single FPGA in cognitive network. By analyzing the processing ability of FPGA and evaluating the existed architecture, this framework based FPGA supplying more logic resources and stronger embedded...
