Pilot Assisted Visible Light Communications
Abstract: The pilot-assisted peak-to-average power ratio (PAPR) reduction technique for optical orthogonal frequency division multiplexing (OFDM) communication systems is simulated, analysed and empirically evaluated. The PAPR reduction is achieved by rotating the phase of data symbols with P iterations of randomly generated pilot symbol sequence. The results of our hardware implementation show a close agreement to that of computer simulations. Furthermore, we have obtained closed-form expression for complementary cumulative distribution function (CCDF) which shows close agreement with simulated results. In comparison with basic OFDM, where no PAPR reduction technique is implemented, experimental PAPR reduction gain of pilot-assisted OFDM (PA-OFDM) at a CCDF of 0.01 with P = 5 is about 1.6 dB. Furthermore, experimental results show that PAPR reduction gain increases as CCDF value decreases. The simulation and experimental results also show that the pilot-assisted technique does not cause deterioration of the bit error performance.

Design Considerations for High Speed Visible Light Communication Systems
Abstract: Visible light communications (VLC) has potential to play a major part in the future smart home and future generation communication networks. There had been significant improvements in VLC technology in the last decade and a multi-Gigabit data rate is possible using light emitting diodes (LEDs). The commercial success of VLC systems, however, depends on the ability to fabricate low cost transceiver components and to realize the promise of high data rates. This talk focus on a new approach to establish the device parameters for integrated VLC system design by taking account of particular characteristics of the emitter and a receiver technology and combining them with power requirement for a particular modulation scheme. Different approaches including multiple inputs multiple outputs (MIMO), spatial modulation and ganging schemes to achieve high data rates will be discussed. The talk also highlights challenges in achieving highly parallel data communication along with the possible bottlenecks in integrated approaches will also be discussed. A new approach of generating a large bandwidth (in excess of 200 MHz) white light using a blue LED and super-yellow color converter will be highlighted.

Patch based digital image processing – Principles and selected applications
Abstract: We are witnessing rapid emergence of patch based, non-local digital image processing techniques. During the last decade, these techniques led to tremendous improvements in denoising, deblurring, inpainting, superresolution and many other image processing tasks. By modeling and manipulating patches of image pixels and by considering and grouping similar contexts non-locally, throughout the image, these approaches improve strongly over the more traditional pixel-based and local techniques. In this talk, we review some of the basic principles of patch-based image processing, from modeling and grouping of self-similar patches to learning dictionaries of patch-based image atoms. Selected applications in image restoration, super-resolution and inpainting will be discussed.

Myoelectric Prosthesis Control: The gap between academia and industry
Abstract: An artificial arm, or prosthesis, is an example of technology that can be used to help somebody perform essential activities of daily living after a serious injury that results in the loss of their arm. Such activities might include eating, washing, opening doors, or shaking hands with a friend. Many artificial arms on the market these days are highly sophisticated, offering individual finger movement, and even movement of segments within a finger, that resemble the natural arm and hand. These prosthetic arms are often controlled by sensing the contractions in the muscles of the remaining arm to which the prosthesis is attached, allowing the user to operate the arm by flexing their muscles. However, still some everyday tasks, e.g. tying a shoe-lace, are currently challenging with prosthetic hands. In this talk, I will introduce the state-of-art of prosthesis control in academia and industry and discuss how the gap between what is possible in the laboratory and what is available in clinic could be reduced.

Multicarrier modulation in optical wireless communications
Abstract: Multicarrier modulation (MCM) technique permits the parallel transmission of data along a number of sub-channels to increase capacity and/or combat channel impairments. This technique is also termed subcarrier modulation and can be configured such that the sub-channels are orthogonal with the nomenclature orthogonal frequency division multiplexing (OFDM).

Peak-amplitude-aware Precoded MIMO Systems
Abstract: In this talk, topics related to peak-to-average power ratio (PAPR) reduction and related precoding techniques of the transmit signal in multi-input multi-output (MIMO) space division multiplexing (SDM) transmissions are mainly presented.

Space-enabled Future Smart Cities: A Review of Technologies and Resources
Abstract: Satellite-enabled applications and services have continued to enhance the global economy and sustainable development on a daily basis. It is predicted that capability-based space satellite missions and applications will revolutionise the emergence of smart cities in 5 to 10 years from now. The various stakeholders in the space community (including the satellite industry, military, civilians, government, corporate organisations, educational and research institutions, agencies and ICT practitioners) have embraced the challenges of the requirements of space-enabled smart cities. This has resulted in an unprecedented increase in the number of new international space entrants, collaborative research and technology developments and product offerings for innovative services. The ultimate global experience is a growing seamless merging of adaptive space assets with terrestrial assets. Current and emerging digital and RF/microwave engineering systems have championed the majority of the innovative services proposed for the future intelligent cities. It is essential to investigate the existing and emerging systems technologies, multifunctional network platforms and protocols, space segment assets and ground segment resources and how they can be integrated and optimised to provide commercially cost-effective, sustainable, reliable, capability-based and real-time services for future smart cities.
