Abstract

  • This course presents recent research developments in the area of wireless communications.
  • We emphasize promising techniques to be used at the physical and MAC layers allowing a significant increase in the network's spectral efficiency (Bit/Sec/Hz).
  • In particular, we describe 1) space-time (multiple antenna) signal processing techniques such as MIMO techniques, and 2) adaptive coding and modulation.
  • We also look at joint adaptive MIMO coding/modulation design.
  • We illustrate the impact of these advanced techniques on the overall network's performance.
