Eligibility:


In order to be eligible for a second cycle course the applicant needs to fulfil the general and specific entry requirements of the programme that owns the course. (If the second cycle course is owned by a first cycle programme, second cycle entry requirements apply.)
Exemption from the eligibility requirement: Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling these requirements.

Course specific prerequisites

A passing grade in SSY125 Digital Communications, or a similar course, is required.

This implies working knowledge of basic concepts in signal processing (linear filtering, convolution, impulse response, frequency response, Fourier transforms), probability and random processes (probability density functions, conditional probabilities, expectation, power spectral density), modulation (pulse-amplitude modulation, quadrature modulation, intersymbol interference), error-control coding (block codes, convolutional codes), error probability analysis for additive white Gaussian (AWGN) channels, power efficiency, and spectral efficiency, and channel capacity for AWGN channels. Basic MATLAB skills programming skills are required to complete the course projects.

Aim

The course is concerned with design of wireless communication systems. This includes link design (i.e., choice of modulation, channel coding, and possible use of multiple antenna techniques), channel access design (i.e., choice of multiple access, multiplexing, and duplexing techniques), and network design (e.g., choice of cell layout, power control, frequency and channel reuse strategies). Wireless channel models, coding, and modulation are particularly emphasized. The aim is that the students will acquire enough understanding of the wireless channel and the state of the technology to explain why today's systems are designed as they are and how they can be improved as technology evolves.

Learning outcomes (after completion of the course the student should be able to)

  • explain why small-scale and large-scale fading occurs
  • describe the conditions under which the standard path loss and fading models accurately predicts real-world radio wave propagation
  • define Doppler spread, delay spread, coherence time, and coherence bandwidth and explain how these parameters are related and affect the wireless physical layer design
  • define the performance metrics instantaneous error probability, average error probability, and outage probability and understand which metric is appropriate for a given scenario
  • define ergodic and outage channel capacity and explain under which conditions these concepts indicate the spectral efficiency of an optimum link design
  • evaluate the performance of communication links over fading channels by analysis and computer simulations
  • define the concepts of channel reuse, uplink, downlink, multiple access, multiplexing, frequency-division, time-division, code-division, and space-division
  • define the concepts of time, frequency, and space diversity and explain how diversity can be achieved in practice
  • explain the concept of spatial channels for multiple input, multiple output (MIMO) systems
  • describe and compare complexity and performance of the following channel equalizations methods: zero-forcing, linear MMSE, maximum likelihood
  • design and interpret power and rate allocation algorithm, including statistical and deterministic water-filling
  • explain the effect of phase noise and power amplifier nonlinearities on the communication link
  • describe the current knowledge of health effects of electromagnetic radiation and how this affects the design of wireless communication equipment via regulations, recommendations, and measurement methods for determining safe levels of exposure
  • describe the foundations for ethical scientific research (e.g. related to dual use, data collection, plagiarism and authorship)
