Introductory description

This module aims to provide the students with an up to date, comprehensive knowledge of the main wired and wireless communications technologies that are used, or will be used, in current and future production consumer vehicles.

Module aims

Through providing a knowledge base of core telecommunications theories, the student is taken forward into the application domain, such that the various wired and wireless technologies in the context of the automotive space is understood. Key concepts of theory vs. application are discussed based upon the inference and understanding of the performance of the technologies both at the component and system level. Topics are introduced from both the theoretical and practical viewpoints to encourage independent critical evaluation of the subject matter.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Introduction: Taxonomy of modern communications. OSI Model. Context of Networks and Communications.

Telecommunications Theory:

  • Pulse Modulation: Analog to digital conversion. Sampling, aliasing, and Nyquist, Equalisation. Digitisation, quantisation and errors. Encoding and decoding.
  • Baseband and Passband Modulation: baseband and applications of baseband transmission. ISI. Pulse shaping Baseband to pass-band. Carrier waves. Basic modulation types. Error rates and bandwidth relationships.
  • Coding Theory: BER, basic coding schemes, AWGN. Error detection and correction, basic ECC Shannon limits and/or capacity.
  • Multiple Access: Single channel communications. Multiple access motivation and techniques. Multiple access in practice.

Wireless Technologies

  • Link Budget and Channel: Spectrum Reuse. Noise, origins and types. Free space losses. Carrier to Noise Ratio. Propagation models.
  • GNSS: Core principles and motivation in the context of automotive. Performance metrics. Automotive integration.
  • WiFi and the Unlicensed Spectrum: The unlicensed spectrum and considerations. WiFi standards, MAC and PHY. Architectures. LTE-U, regulations. Move to higher frequencies.
  • 5G: Key Technologies and Roadmap for 5G. Background and Demands. 5G Specifications. Absorptions and specific channel limitations. OFDM/multicarrier transmitter and receiver. Convergence including IoT. Backward (and forward) compatibility.

Wired Technologies

  • CAN/CAN-FD: Context and principle applications. Physical layer (low speed and high speed), and architecture. Protocol - Message frames, headers, addressing, message IDs. Usage and standards compliance.
  • LIN: Context and principle applications. Physical layer. Protocol - Message frames, headers, addressing etc. Topology. Usage and compliance. API.
  • Ethernet: General Ethernet principles. Networking model, and comparison between other technologies. Terminology. Standards. Topologies e.g. bridges, nodes, stations etc. Common physical layers and IEEE 802.3.
Learning outcomes

By the end of the module, students should be able to:

  • Critically evaluate different communication building blocks and how they might be integrated together within a connected and/or autonomous system
  • Evaluate a complete communication system within the wider automotive eco-system and understand what is currently considered as state-of-the-art, with an enhanced research view of the future
  • Apply relevant practical communications techniques appropriately and understand how their results may be used to inform judgements, develop and advance ideas and/or practice.
  • Demonstrate the ability to design communication systems to support connectivity aspect of connected and/or autonomous systems within the backdrop of Intelligent Transportation Systems network.
  • Demonstrate a comprehensive understanding of and competence in the use of appropriate channel modelling tools and techniques for the purpose of system performance prediction.

Costs

Category Description Funded by Cost to student
Equipment and project costs

The laboratories may require disposables in the forms of cables and connectors which get damaged around the main equipment. The CAN laboratories are hands on and students should interact, re-wire and re-configure on the day. This may lead to further breakages.

Potential for £1000 per year for replacements on such items.

Dr Ahmet Er has previously approved this.

 Department £0.00
