Summary

With an explosion of wireless mobile devices and services, Wireless system designers have been facing the continuously increasing demand for high data rates and mobility required by new wireless applications and therefore have started research on fifth generation wireless systems that are expected to be deployed beyond 2020. Future challenges facing these potential technologies are the significant increase in the complexity of RF cellular handset communication systems that use massive MIMO and cognitive radio networks.

This course is intended for engineers wanting to learn about the fundamentals of handset RF architectures, including aspects of the radio design covering the entire signal chain from the RF input (High performance passive/active circuits for RF/mm-wave front-ends) to the A/D Digital interface. The aim is understanding system design methods to dissect the different radio architectures with emphasis on the physical layer (RF) for the most advanced commercial LTE and the new MIMO-5G systems.

Learning objectives

Upon completing the course you will be able to:

  • Gain in-depth understanding of The trade-offs between Digital Modulation Techniques and RF Performance and how this relates to system level performance metrics (e.g. C/No, BER, EVM)
  • Interpret key RF parameters such as Noise figure (NF), Sensitivity, Spurious free Dynamic range, Intermodulation distortion, Calculations - P1dB - IM2 - IP2 - IM3 - IP3 - Cascaded IIP3, Power Added Efficiency (PAE), Adjacent Channel Leakage Ratio (ACLR), Peak-to-Average Power Ratio (PAPR)
  • Understand the trade-offs between block-level performance, choice of radio architectures and overall system performance (e.g. power, area and cost) in relation to a given communication standard
  • Appreciate the improved performance offered by MIMO techniques, advanced RF front ends and Smart Antenna Solutions.
  • Understand architecture trade-offs for Active/Passive circuits for RF/mm-wave front-ends

Target Audience

RF and baseband IC engineers, system architects, test and product engineers. Technical managers who would like to get exposure to RF smartphone technology.
