Green applications for consumer electronics and engineering sustainability remains as an essential aspect of providing effective portfolio for delivering cost savings systems for smart cities that will enable the achievement of energy saving, carbon reduction and environmental sustainability. The issue of virtual usability and awareness management strategy may result in achieving excellence in energy efficiency and usage, environmental considerations and energy re-use strategic models for smart cities. The return on investment (ROI) as strategic outcome of green application model may restore and create value analysis for organizations with huge energy wastage without thinking of cost, environmental impact and carbon emissions. Green consumer electronics and sustainability for smart cities, smart living and digital diversity are recent development of the creative computing technologies for future generation communications agenda which contributes towards new wave industrialization and commercialization in terms of virtual applications and service delivery through the internet for the purpose of cost benefit, usability of business and enterprise services. Green computing is defined in various contexts, environmentally, socially and politically with respect to effective and efficient use of energy to achieve competitive advantage in terms of an energy-cost saving strategy, and reduction to carbon emission/footprints, recyclability, biodegradability, and minimal impact to the environment. Smart cities will benefit from the effective deployment of cloud computing through the concept of delivering virtual services and internet medium using consumer electronic devices to achieve competitive edge with respect to cost savings, improvement of performance, efficiency and effectiveness. The services may focus within the different service platforms of cloud computing such as: public cloud, private cloud, hybrid cloud, community cloud, education cloud and enterprise cloud. The choice of the best application portfolio services will depend on value analysis, cost savings, improve performance, competitive edge and marketization of the deliverables and monetization, in terms of financial benefits for the government, business and industrial sectors as enabler for the achievement of smart living, health and wellbeing.

Orthogonal frequency division multiplexing (OFDM) is a promising multi-carrier modulation technique and has been widely used for wireless communications systems. OFDM is inherently high-bandwidth efficient, but we cannot avoid bandwidth inefficiency to remedy the increased peak-to-average power (PAPR) issue in OFDM systems. In this talk, we consider the bandwidth inefficiency issue of some PAPR reduction techniques for OFDM systems. These techniques are effectively combined with a concept of subcarrier group modulation (SGM) to be proposed, resulting in schemes which accomplish bandwidth efficient communications. The available subcarriers are divided into a number of groups and each group is modulated. Then at the receiver side, a maximum likelihood detector is used to catch up the modulation information. The resulting schemes attain low PAPR without compromising their throughput. Some simulations results are shown and it is unveiled that SGM is an interesting idea and plays an important role for OFDM systems.
