Digital Communications

The term digital communications cover all communication systems, networks and services where the information to be exchanged and processed is given a digital representation in terms of bit representations and digital signals, and processed by means of digital signal processing. The information at hand can represent for example multimedia signals (video, audio, speech, other forms of data), with applications e.g. in mobile cellular telephony (GSM, UMTS), broadcasting (DAB, HDTV), Broadband for All (ADSL, WLAN, fixed wireless access), entertainment and gaming, aeronautical and deep-space communications, and Internet applications at large. It can however also represent digitized measurements of almost any kind of physical process (such as temperature, pressure, chemical concentrations, trajectories of moving objects) in applications ranging from medical and environmental monitoring to industrial automation, automated highways, intelligent homes, surveillance and military applications.
