What You Will Study

Unit 1 — Introduction to Digital Communication (6 Periods, 14%)

Overview of digital communication systems, Analog vs. digital communication, Elements of digital communication systems, Basics of information theory, entropy, relationship between information theory and communication systems.

Digital vs analog communication, the parts of a digital link, and information theory — entropy and how much information a channel can carry.

Unit 2 — Modulation Techniques (10 Periods, 24%)

Pulse Amplitude Modulation (PAM), Pulse Position Modulation (PPM), Pulse Width Modulation (PWM). Pulse Code Modulation, Basic concept of sampling theorem, quantization, coding and Shannon’s theorem, Types of PCM system and its application (Basic idea only). Basic idea of: Amplitude Shift Keying (ASK) modulation and demodulation technique, Frequency Shift Keying (FSK) modulation and demodulation technique, Phase Shift Keying (PSK) modulation and demodulation technique, Quadrature Amplitude Modulation (QAM) modulation and demodulation technique

How digital data rides on an analog carrier: pulse modulation, PCM and the sampling theorem, and ASK, FSK, PSK and QAM.

Unit 3 — Error Control Coding (8 Periods, 19%)

Introduction to channel coding, Basics of code theory, Error detection and correction codes, Block codes and Convolution codes, Introduction to error detection and correction technique.

Adding clever redundancy so the receiver can spot — and fix — errors: block codes and convolutional codes.

Unit 4 — Multiplexing and Multiple Access Techniques (8 Periods, 19%)

Frequency division Multiplexing (FDM), Time division Multiplexing (TDM), Code division Multiplexing (CDM), Basics of orthogonal frequency division Multiplexing (OFDM). Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Orthogonal Frequency Division Multiple Access (OFDMA)

Sharing one channel among many users: multiplexing by frequency, time or code, and the multiple-access schemes built on them (FDMA, TDMA, CDMA, OFDMA).

Unit 5 — Digital Transmission Fundamentals and Performance Analysis (10 Periods, 24%)

Line coding techniques (NRZ, RZ, Manchester), Baseband and passband transmission, Signal-to-noise ratio (SNR) and bit error rate (BER), Channel capacity, Shanon-Hartley theorem, Link budget analysis, Brief idea of interference and noise in digital communication systems.

How good a digital link is: line codes, SNR and bit error rate, channel capacity (Shannon-Hartley), and link budgets.
