Introduction
This unit introduces the fundamental concepts of modern communication systems. On completion of this unit you will be able to design and construct a digital communication system. The unit begins with an introduction to signaling theory and the modulation theorem. The communication channel will then be explained using additive white Gaussian process. Minimising the distortion while demodulating the signal in the presence of noise will be shown with considering the effects of noise equivalent bandwidth, signal to noise ratio and bandlimited processes. This all relates to the fundamental Nyquist signaling theorem. Design trade-offs in amplitude and angle modulation using suppress carriers. Demodulation design considerations in power and bandwidth limited systems for coherent and noncoherent carrier phase locked receiver will be investigated. The fundamentals of digital signal theory is then explored to create signal constellation diagrams using Gray coding. Amplitude, frequency and phase shift keying will be introduced, with explaining the maximum aposterior probability and maximum likelihood detectors for non-dispersive channels. Design consideration of bandwidth and power efficiency, carrier-to-noise ratio, and selecting modulation schemes will be shown. The unit concludes with introduction to information theory, with application of the source coding theorem using the Huffman algorithm and Lempel-Ziv method. These are fundamental communication topics required for advanced telecommunication systems used in any embedded systems, automation, advanced communication systems and which are studied later in the degree.
