Overview

The course begins by covering fundamental digital signal concepts. We look at the relationship between complex digital signals and the hardware (specifically complex envelope, quadrature modulators and demodulators). This will also be used to provide insight into the modulation schemes chosen by these standards.
Understanding the evolution of wireless data transmission from 3G to 4G technologies is critical to today’s commercial component and system vendors. This comprehensive three day program covers the key technologies in a clear and concise manner.

What you will Learn

  • Understand multipath fading issues when deploying WCDMA and LTE.
  • Describe receive antenna diversity techniques and issues surrounding their implementation.
  • Compare the implementation complexity of TDMA, CDMA and OFDMA as the supported data rates increase.
  • Know the issues and obstacles related to multiple access schemes and how to overcome them.
  • Address issues pertaining to timing tracking and channel estimation.
  • Describe the expected UE behavior with regards to cell search.
  • Address the timing requirements for closed loop power control.
  • Describe various LTE system scenarios such as random access and link adaptation.

PREREQUISITES

  • Engineers and technical managers who need a technical understanding of third and fourth generation cellular data transmission techniques will benefit from this course. Knowledge of fundamental signal processing concepts (Fourier transform, etc.) is assumed.
