Aim:
After passing the course, the student should
- be able to reliably perform standard calculations regarding digital modulation, binary (linear) codes for error control and source 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 and related concepts.
- be able to account for practical problems that arise in communication, and be able to account for possible solutions to those problems.
- to some extent be able to perform calculations for solutions to practical problems that arise in communication.
- with experimental purpose be able to evaluate and to some extent implement such communication systems that are 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 Signals, information and communication: Channel models, baseband representation of narrowband signals, the entropy concept.
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:
Digital communication Continuation Course, Wireless systems, Radio communication, Error correcting codes, Source coding, Image and audio coding.
|
|
Organisation:
Teaching is given as lectures, tutorials and laborations.
The course runs over the entire autumn semester.
|
|
Course contents:
- Signal-theoretic basics: Auto-correlation and power spectral density.
- Digital modulation: The vector model, ML detection, MAP detection, error probabilities, coherent detection. Common signal constellations, like FSK, PSK, QAM. Multi-dimensional signal constellations: OFDM.
- Codes for error control: Binary-symmetric channels. Binary linear codes, repetition codes, simple parity check codes, Hamming codes, dual codes, product codes, cyclic codes and CRC codes. The sphere packing bound and the Singleton bound. Basic parameters like length, dimension, size and minimum distance. Weight and distance distributions. Error detection and correction capabilities.
- Practical aspects: Eye patterns, synchronization, colored noise, intersymbol interference, non-coherent detection.

The exam (TEN1) consists of three parts:
- One introductory task that examines the course aims "be able to reliably perform standard calculations...". At least 1/2 of this task has to be solved correctly in order to pass the exam.
- A question part, examining the learning outcome "be able to account for..."
- A problem part, examining the learning outcomes "be able to, with some precision,..." and "to some extent...".
The grade on the exam is based on the number of points obtained from the second and third part, provided that the first part is OK.
The laborations (LAB1) examines the course aim with experimental purpose.. |
Course language is Swedish/English.
Department offering the course: ISY.
