Prel. scheduled hours: 56
Rec. self-study hours: 104

  Area of Education: Technology

Main field of studies: Electrical Engineering

  Advancement level (G1, G2, A): A

Aim:
After passing the course, the student should
  • be able to reliably perform standard calculations regarding digital modulation and binary (linear) codes for error control coding
  • be able to, with some precision, analyze and compare various choices of digital modulation methods and coding methods in terms of error probabilities, minimum distances, throughput, and related concepts
  • be able, to some extent, to perform calculations for solutions to practical engineering problems that arise in communication
  • be able, to some extent, to implement and evaluate communication systems of the kinds treated in the course


Prerequisites: (valid for students admitted to programmes within which the course is offered)
From Calculus: Foremost integrals.
From Linear algebra: Everything related to linear spaces.
From Signals and systems: Fourier transforms, convolution, LTI systems.
From either “Signals, information and communication” or “Signals, information and images”: pulse-amplitude modulation, white noise, baseband representation of narrowband signals, channel capacity.


Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.

Supplementary courses:
Detection and estimation of signals, Wireless communication, Multiple antenna communication, Modern channel coding, inference and learning

Organisation:
Teaching is given as lectures, tutorials and laboratory exercises.

Course contents:
    Baseband and passband communication: Pulse functions that satisfy the Nyquist criterion, typical orthogonal basis functions, single-carrier and multi-carrier signals (e.g., OFDM), relationship between bandwidth and symbol time.
    Channels: Delay spread, dispersive and non-dispersive channels, and their relation to inter-symbol interference.
    Digital modulation in AWGN channels: ML detection of symbols, coherent and non-coherent detection. Exact error probabilities and common bounds, soft decisions. Common signal constellations (e.g., FSK, PSK, ASK, QAM).
    Digital modulation in dispersive channels: ML detection of symbol sequences, complexity considerations, Viterbi algorithm.
    Codes for error control: Binary linear codes, binary field, generator and parity check matrices, weights and distances. Error detection and error correction capabilities. Example of binary codes (e.g., repetition codes, parity check codes, Hamming codes, product codes). Bounds and asymptotic behaviors. Convolutional and CRC codes.
    Implementation aspects: Eye patterns, synchronization, link adaptation in packet transmission.


Course literature:
Mikael Olofsson, Emil Björnson, Introduction to Digital Communication, Institutionen för Systemteknik (ISY), Linköpings universitet, with accompanying problem material, and also some extra material that will be handed out during the course.

Examination:
Written examination
Laboratory work
5 ECTS
1 ECTS
 
The exam (TEN1) examines the first three course aims, while the laboratory work (LAB1) examines the last course aim. The final grade is determined by the exam result.



Course language is Swedish/English.
