The fusion of digital and real worlds in all dimensions will be the driving force for future sixth-generation (6G) wireless systems. Ubiquitous in-time and on-time communication services between humans, machines, robots, and their virtual counterparts are essential, and they expand from the ground to air, space, underground, and deep sea. 6G systems are not only data pipelines but also large-scale distributed computing systems […]

In the imminent era of 6G communications, unprecedented advancements will reshape our technological landscape and redefine the boundaries of the digital experience. 6G will enable two main features: ubiquitous communications via satellite-terrestrial integrated networks and intelligent connections. It is expected that 6G will significantly amplify network capabilities through advanced communication techniques such as AI methods […]

6G networks will bring forth a variety of novel enabling technologies such as integrated sensing and communications for perceptive mobile networks, quantum-enabled wireless networks, blockchainized mobile networks, and AI-native networks with intelligence-endogenous capabilities. The push from more advanced technological tools becoming available as well as the pull from society’s needs imply that there must be […]

In this talk, we will first review the model of linear time-varying (LTV) channels from the delay-Doppler (DD) domain, and discuss the LTV channels' DD domain impulse response. Next, we revisit the fundamentals of multi-carrier (MC) modulation, including the transmission strategy, the pulse design principles and the implementation methods. Then, we propose an impulse function […]

MIMO (multiple-input multiple-output) wireless communication has been an instrumental technology in fourth and fifth generation cellular communication systems. With more aggressive performance targets, the evolution of MIMO is essential to support more antennas,  accommodate larger bandwidths and exploit higher carrier frequencies.  In this talk, I will describe three areas of opportunity for the next generation […]

A highly competitive research environment with increasingly limited research funding has created a “Publish or Perish” attitude among scientists who are judged on the quantity rather than quality of their research articles. This presentation provides a brief overview of current trends and challenges in scientific publishing, some ethical considerations, how publishers and authors interact and […]

This presentation discusses various aspects of Compressed Spectrum Sensing (CSS) systems to address existing challenges and enhance practical implementation. The research contributes to some of the key techniques that enhance the performance of CSS systems in a practical framework, including refining spectrum recovery accuracy, optimising sampling pattern design, and improving reconstruction and machine learning algorithms. […]

Kerr optical frequency combs have emerged as one of the most versatile laser sources over the past decade. Through the nonlinear cavity soliton generation process within a Kerr resonator, a narrow linewidth coherent laser can be efficiently broadened into a wide-ranging comb, with all comb lines remaining mutually coherent. In the quest for miniaturization, the […]

The propagation of short and intense laser pulses in an optical fiber is known to be associated with a rich landscape of nonlinear propagation scenarios and multidimensional dynamical regimes. For example, in the coherent regime, soliton dynamics can lead to the generation of a broadband supercontinuum while in the incoherent regime noise amplification can lead […]
