In this chapter, based on definitions of signal synthesizers and analysers, a general and generic scheme of a discrete communication system is developed in order to deduce practical systems as its special cases. The synthesizer is transferred into a discrete transmitter, and the analyser is used as a correlation receiver followed by an optimum detector. The system structure is presented in terms of mathematical operators and supported by exact mathematical expressions based on the theory of discrete-time stochastic processes. The likelihood function is derived, and the maximum likelihood rule is applied to specify the decision process and construct the optimum detector. A multilevel system and a quadrature phase-shift keying system are deduced as special cases, and the bit error probability expression is derived. For the sake of continuity and completeness in presenting communication systems theory, a generic digital communication system is developed and related to its discrete counterpart.

BackgroundPoor communication to GPs at hospital discharge threatens patient safety and continuity of care, with reliance on discharge summaries commonly written by the most junior doctors. Previous quality improvement efforts have largely focused on adherence to standardised templates, with limited success. A lack of understanding has been identified as a cause of the issue’s resistance to decades of improvement work.AimTo understand the system of communication to GPs at hospital discharge, with a view to identifying potential routes to improvement.Design, SettingA qualitative exploration of the secondary-to-primary care communication system surrounding a UK tertiary hospital.MethodA ‘systems approach’, recently defined for the healthcare domain, was used to structure and thematically analyse interviews (n=18) of clinical and administrative staff from both sides of the primary-secondary care interface and a subsequent focus group.ResultsThe largely one-way communication system structure and the low level of hospital stakeholder insight into recipient GP needs emerged as consistent hindrances to system performance. More open lines of communication and shared records might enable greater collaboration to share feedback and resolve informational deficits. Teaching sessions and assessments for medical students and junior doctors led by GPs could help to instil the importance of detail and nuance when using standardised communication templates.ConclusionFacilitating the sharing of performance insights between stakeholder groups emerged as the key theme of how communication might be improved. The empirical measures proposed have the potential to mitigate the safety risks of key barriers to performance, such as patient complexity.

New Type

From several basic structures for indoor computer wireless communication system, a new type of system structure was designed. Its conformation of optics system and achievement by module were described particularly through using Fresnel lens system. This system’s link could be transformed between directed LOS link and non-directed LOS link, which made the system communicate at a high-speed when there were no barriers between the emitter and receiver and keep a good convexity when barriers appeared. At last what should be noted for the analogue simulation was brought up.

Communication System Design

Hybrid free space optical/radio frequency communication systems improve reliability of links. However, independent communication subsystems increase the system complexity, weight, size, and power consumption. Based on microwave photonics, a unified hybrid free space optical/radio frequency communication system design is proposed. The communication subsystems share antenna, modulator, and demodulator to simplify system structure. Operating principle is expounded by theoretical reference, and 3dB theoretical loss is found in millimeter-wave communication mode.

Fifth Generation (5G) networks hold the promise of features and performance levels that is going to put the conventional cellular communication paradigm through rigorous challenges. This paper presents a novel architecture for a 5G network which will be capable of mobile device centric communication regardless of the presence of a Base Station (BS). The major contribution of this paper, lies in the proposed system and protocol design of a Device-to-Device (D2D) communication system for 5G mobile system. The proposed design has two sub-categories – (a) fully device centric and (b) partially device centric. Additionally, the devices have been designed to communicate independently or with partial dependency on support from the BS. The system has been simulated under various parameters. The simulation results showcased in this paper highlights the efficiency and effectiveness of the proposed design.

Software-defined networking offers several benefits for networking by separating the control plane from the data plane. However, networks’ scalability, reliability, and availability remain as a big issue. Accordingly, multicontroller architectures are important for SDN-enabled networks. This paper gives a comprehensive overview of SDN multicontroller architectures. It presents SDN and its main instantiation OpenFlow. Then, it explains in detail the differences between multiple types of multicontroller architectures, like the distribution method and the communication system. Furthermore, it provides already implemented and under research examples of multicontroller architectures by describing their design, their communication process, and their performance results.

Factory Automation

Factory automation (FA) is a direct result of the underlying communication systems. To integrate the FA information and make FA control systems with flexibility and interoperability in automated manufacturing systems, the manufacturing message specification (MMS), Web services’ (WSs) technologies and typical FA systems are analyzed. A new design approach of the communication system structure is presented for FA systems in this paper. A prototype of FA control systems is used for evaluating performance of the communication system structure in C++ Visual Studio.NET and Java Borland Builder 9.0 development environment. The experimental results show that the proposed design approach is valid and promising.
