Device-to-Device (D2D) communication is considered as one of the key technologies for the fifth generation wireless communication system (5G) due to certain benefits provided, e.g. traffic offload and low end-to-end latency. A D2D link can reuse resource of a cellular user for its own transmission, while mutual interference in between these two links is introduced. In this paper, we propose a smart...
The application of Mission Critical Machine Type Communication (MC-MTC) in wireless systems is currently a hot research topic. Wireless systems are considered to provide numerous advantages over wired systems in e.g. industrial applications such as closed loop control. However, due to the broadcast nature of the wireless channel, such systems are prone to a wide range of cyber attacks. These range...
Compared with today’s 4G wireless communication network, the next generation of wireless system should be able to provide a wider range of services with different QoS requirements. One emerging new service is to exploit cooperative driving to actively avoid accidents and improve traffic efficiency. A key challenge for cooperative driving is on vehicle-to-vehicle (V2V) communication which requires...
Billions of Machine Type Communication (MTC) devices are foreseen to be deployed in next ten years and therefore potentially open a new market for next generation wireless network. However, MTC applications have different characteristics and requirements compared with the services provided by legacy cellular networks. For instance, an MTC device sporadically requires to transmit a small data packet...
Massive machine type communication (mMTC) to serve billions of IoT devices is considered to offer the potential to open a potential new market for the next generation cellular network. Legacy cellular networks cannot meet the requirements of emerging mMTC applications, since they were designed for human-driven services. In order to provide support for mMTC services, current research and standardization...
We analyze the performance of an orthogonal frequency-division multiplexing interleave-division multiple access (OFDM-IDMA) system for channels with a carrier frequency offset. First we introduce a vector-valued transmission model for the OFDM-IDMA system, including an improved chip detector. A semi-analytical technique is applied to generate variance transfer charts and predict the performance of...
Device-to-Device (D2D) communications is considered as one of the key technologies for 5G wireless communications system, since it offers several advantages compared with traditional cellular network, i.e. low end-to-end latency and high spectral efficiency. By allowing underlaying direct D2D communications, a D2D link which reuses the spectral resources of a cellular user causes increased interference...
