As the Internet model created an environment for creativity and innovation, so, too, will the new Internet protocol multimedia subsystem (IMS) based on the session-initiation protocol (SIP) and Int
We will give an overview of our research on flexible bitrate PON with increased overall throughput or with an extended reach and power budget.
Overview of using flexibility to increase overall PON throughput, to extend optical power budget, and to reduce energy consumption in future optical access networks.
Optical access networks have been widely adopted to support the exponential growth in bandwidth demand.
In this paper we propose a flexible 50G PON based on CAP (carrier less amplitude phase) modulation and compare this with our user interleaving PAM-4 scheme at 50G as well.
In November 2015 the latest world radio conference took place and as a result the below 6 GHz RF bands have become more important for 5G in the foreseeable future.
The introduction of HTTP Adaptive Streaming enabled high quality video delivery over IP networks. The continued rapid growth in video traffic poses new challenges at the network management level.
Spectrum resources unused in the spatio-temporal domain, so-called whitespace, can be utilised by opportunistic devices during the absence of their incumbent users.
We review flexible bitrate systems supported by variable symbol rate and varable spectral efficiency.
Support of wider bandwidth up to 100 MHz is one of the key features for IMT-Advanced system. Carrier aggregation has been studied as major a solution.
