Course content

The course gives a fundamental introduction to the principles and systems for digital transmission of information over channels with Gaussian noise, including basic transmission and reception strategies, as well as an understanding of expected performance and performance limits. Through project work, the course gives the student skills in simulation of and experimentation with real transmitter and receiver hardware, as well as experimentation planning and reporting. The couse topics are: - Linear baseband digital (PAM) modulation, - upconversion and linear (QAM) and nonlinear (FSK) passband digital modulation, - Maximum a-Posteriori and Maximum Likelihood detection, non-coherent detection, - transmissiond bandwidth, Nyquist pulses, sampling and intersymbol interference, - Gaussian noise, and related error analysis in symbol detection, - Gaussian channel capacity, coding, convolutional codes, decoding, and error analysis, - signal space, signal constellations, equivalent baseband model, and - tradeoffs between energy, data rate and error rate.

Learning outcome

Knowledge: The candidate has: - understanding of digitally modulated signals and their properties, - deep understanding of the detection principles for digital signals, - good understanding of error behavior and performance of digital receivers - understanding of central abstraction methods and models used to describe digital transmission methods - good overview of performance limits. Skills: The candidate can: - construct or parametrize digital transmitters and corresponding receivers, - characterize the central qualities and performance of digital transmission through simulation and analysis, - find tradeoffs between energy, bandwidth, and error rate, - evaluate performance limits, and - execute simulations and real-life communication experiments using experimental radio units.

Learning methods and activities

Lectures and integrated exercises. Project work in groups, with supervision.

Compulsory assignments

  • Feedback activity

Further on evaluation

In the final grade, the written exam weighs 55%, and the projects weigh 45%. The projects are graded as follows: each of the three projects is given points between 0-33. All students in a project group receive the same points, and the project grade for the student is given based on the sum of points from the three projects, plus one. The students are given written, formative, feedback, before the final deadline of each report. Information on the deadlines for the reports are announced via Blackboard at the beginning of the semester. Reports are delivered via Blackboard.

The obligatory deliveries consist of reflection notes on students' own learning.

Repeat exam may be changed to oral exam.

In order to pass the course, a passing grade in the final written exam is required

Specific conditions

Compulsory activities from previous semester may be approved by the department.
