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 â?oSignals, information and communication" or â?oSignals, 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.
