The aim of this module is to gain a general overview of the principles of telecommunications engineering. A more detailed module descriptor can be found on the following address: https://www.maynoothuniversity.ie/electronic-engineering/current-students/module-descriptors The indicative syllabus is as follows: • Overview of communications o Use of communication systems in the real world (mobile phone, satellite television, etc) o The nature of data, analogue/digital, bandwidth requirements – real-time versus non-real-time communications (e.g. phone vs email) o Communication signals – electrical, optical, quantum, electromagnetic (radio) • Communication concepts o Basic communication concepts ¿ Transmitter, receiver, channel, additive noise ¿ Bit rate, power, the dB and dBm – amplification/attenuation/SNR/Noise figures ¿ Point-to-point vs broadcast systems ¿ Channels properties and utility – co-axial cable, twisted pair, optical fibre, air interface o Signals and noise ¿ Communications by means of signals – definition of a signal ¿ Signal characterisation in the time and frequency domain ¿ Analogue to digital conversion of signals ¿ Noise definition – noise margin, thermal noise, white noise, Friis equation o Analogue and digital modulation (and demodulation) ¿ The need for modulation, introduction to basic analogue modulation types (AM/FM) ¿ Introduction to basic baseband and band-pass digital modulation ¿ Study of different types of AM ¬¬– time domain and frequency domain ¿ AM transmitter and receiver architectures o Communication limits and channel multiplexing ¿ Power, noise and channel capacity ¿ Spectrum as a limited resource – spectrum allocation issues ¿ Channel multiplexing – TDM, FDM, spatial multiplexing (GSM use case example) o Communication networks and ethical issues ¿ Communication network topologies – pros/cons, packet concept, congestion concept ¿ Ethical issues related to telecommunications – carbon footprint, security, health
