There is no single and universal definition for ICT (information and communication technology). The term is normally adopted to all devices, networking components, applications, and systems that allow combined people, companies, and organizations (i.e., businesses, nonprofit agencies, governments, and enterprises) to interact in the digital world, the modern era. In this digitally globalized world, we deal with a huge set of data all the time. Data refers to facts, events, actions, activities, and transactions which have been and can be recorded (i.e., the raw material from which information is produced), nurturing the infrastructure and components that enable modern computing. Based on this, the present study aims to implement a discrete events-based model with advanced modulation format DQPSK in a simulation environment, the Simulink of MATLAB software, aiming to improve the transmission of information in communication systems. The results show better computational performance related to memory utilization related to compression of the information, showing an improvement of up to 92.6%.
TopIntroduction
Information and Communication Technologies (ICT) correspond to all technologies that interfere and mediate the informational and communicative processes. Furthermore, they can be understood as a set of integrated technological resources that provide, through the functions of hardware, software and telecommunications, the automation and communication of business processes, scientific research and teaching and learning. The disruptive potential of the current waves of technological innovation related to Information and Communication Technologies, brought changes in several sectors and scopes. An example is the recent educational processes, due to the development and technological independence, are not enough to the learning conditions of the current society, which has the need of independence in the search for information and knowledge construction. This requirement of change is due to the fast technological changes that modern man is subjected to in relation to the digital era and the information in which he finds himself (Chen & Schulz, 2016; Salinas et al., 2017).
Communication is a necessity and something that has been present in human life since the earliest times. Exchanging information, recording facts, expressing ideas and emotions are factors that have contributed to the evolution of ways of communicating. Thus, over time, man has perfected his ability to relate. It is also responsible for great advances, due to the exchange of messages and consequent exchange of experience, was the engine of great discoveries. In the modern world communicating has become a true science where it is necessary to learn all the time to communicate efficiently and effectively, wherein the digital era of social networks transmit the information quickly and concisely. Where digital transformation is not only a concept for the future, but a reality today (Chen & Schulz, 2016).
Digital communication is, first of all, the digitization of the information media, being simultaneously considered and integrated into the communication as a complete ecosystem, an environment that encompasses and acts in the three dimensions. From a pragmatic point of view, digital communication composes the communication actions to be performed on the web, social networks, and mobile devices. Within this framework, emerging ICTs have changed lifestyles and relationships among individuals in modern spaces. From this, the exchange of information across the network and its innumerable communication platforms diffuses new practices of collaborative and creative interaction and provokes more participation society with the modern world, seeking to overcome the limits of the opinion and consulting sphere (Van Laar et al.2017).
Following an increasing tendency in the adoption of information and communication technologies not only by schools, companies, organizations or intuitions of diverse areas, mainly with the dissemination of data and information through the digital devices in the contemporary every day. There is a variety of information that digital processing provides: image, sound, movement, manipulable representations of data and systems, all integrated and immediately available, that offer a new framework of content sources that can be object accessible to all users (Birt et al., 2017).
Based on this, the present chapter aims to present a model of information transmission based on discrete event concepts that provide the improvement of data transmission positively impacting in increasing efficiency in sending and receiving data by reducing the consumption of system memory during this process.
