Modern Telecommunications: Basic Principles and Practices

Description

This is an introductory text that will equip readers with the necessary tools to study telecommunications further. It explains the fundamentals and background behind digital TV, radio, cell phones, and satellites as well as the legacy analogue transmissions. It covers digital modulation and analogue communications as this is something many people still use (VHF FM for example). The book also clearly explains the mathematics and simplifies the process to make it more approachable to students Content: Cover Half Title Title Copyright Contents Preface About the Author 1: Introduction 1.1 Historical Background 1.2 Reasons for Electromagnetic Communication 1.3 Sinusoids: Sines and Cosines 1.4 The Electromagnetic Spectrum: from Submarines to Satellites 1.4.1 ELF, Super Low Frequency (SLF), ULF, VLF 1.4.2 Low Frequency 1.4.3 Medium Frequency 1.4.4 High Frequency 1.4.5 Very High Frequency 1.4.6 Ultra High Frequency 1.4.7 SHF 1.4.8 EHF 1.4.9 Far Infra-Red (FIR), Mid Infra-Red (MIR), Near Infra-Red (NIR) 1.5 Frequency-Division Multiplexing and Frequency Translation 1.6 Tuned Circuits: Station Selection1.7 Basic Radio Receiver Design: The Superheterodyne Receiver 1.8 Three Very Important Theorems: Nyquist (TWICE) and Shannon 1.9 Problems 2: Noise 2.1 Circuit Noise: Why Amplifiers Hiss 2.2 Noise Factor and Figure 2.3 Noise Power from an Antenna 2.4 Cascaded Networks: Friss' Formula 2.5 Noise Temperature and Directional Antennae 2.6 Algebraic Representation of Noise: Filtered Noise 2.7 PROBLEMS 3: Introduction to Digital Modulation 3.1 Pulse Code Modulation: Digitising Signals 3.2 Baseband Digital Signalling: Data Transmission 3.3 Carrier-Based Signalling3.3.1 ASK 3.3.2 FSK 3.3.3 BPSK 3.3.4 Matched Filtering 3.3.5 Orthogonal Frequency-Division Multiplexing 3.3.6 Quadrature Amplitude Modulation 3.4 Coding 3.4.1 Parity Check 3.4.2 Hamming Code 3.4.3 Cyclic Redundancy Code 3.4.4 Convolution Coding, Maximum Likelihood and Viterbi Decoding 3.4.5 Reed-Solomon Coding 3.5 Problems 4: Introduction to Analogue Modulation 4.1 Amplitude Modulation 4.2 Double Sideband Suppressed Carrier Modulation 4.3 Single Sideband Modulation 4.4 Frequency Modulation 4.5 Phase Modulation 4.6 Problems 5: Transmission and Propagation of Electromagnetic Waves5.1 Waves on Transmission Lines 5.2 Reflections and Transmission 5.3 Smith Charts 5.4 Antennae 5.5 Propagation 5.6 Problems 6: Systems 6.1 Satellites 6.2 Ethernet 6.3 Optical Communications 6.4 Mobile Phones 6.5 Digital Audio Broadcasting 6.6 Digital Video Broadcasting 6.7 Wi-Fi 6.8  MIMO 6.9 Asymmetric Digital Subscriber Line 6.10 Bluetooth 6.11 The Intelligent Home 6.12 Software-Defined Radio Appendix I: The Double Balanced Mixer Appendix II: The Product of Two Cosines Appendix III: The Parallel Tuned Circuit Appendix IV: DecibelsAppendix V: Noise Factor and Friss'  Formula Appendix VI: Maximum Power Transfer Appendix VII: Error Function (erf) Tables Appendix VIII: The Discrete Fourier Transform Appendix IX: Summation and Multiplication Tables in GF(8) Appendix X: Bessel Function Coefficients Appendix XI: The Phase-Lock Loop Appendix XII: Lumped Parameters for Coaxial Cable Appendix XIII: The 4B5B Line Code Index
