Basic Concepts in Telecommunications Systems
Journal of Telecommunications System & Management · 2015
Wikipedia defines a telecommunication system in the following terms: “Telecommunication occurs when the exchange of information between two entities (communication) includes the use of technology [1]. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves”. Poor’s definition of a telecommunication system brings out very clearly its intimate relationship to statistics: “Signal detection and estimation is the area of study that deals with the processing of information-bearing signals for the purpose of extracting information from there. Applications of the theory of signal detection and estimation are found in many areas, such as communications and automatic control”. Signal detection is commonly called hypothesis testing in statistics and, it, hand-inhand with estimation, forms the central core of statistics. Thus the importance of statistics for telecommunication systems is inherent in the very definition of these systems [2].
