Course RF100  - Introduction To CDMA And CDMA System Engineering

 

Scope

This five-day course presents the core radio frequency engineering principles applicable to modern wireless RF systems and a thorough yet easy-to-follow introduction to CDMA technology with its unique RF considerations. The course is an effective pathway for engineers and technical personnel from other backgrounds or technologies who want to come up to speed quickly in CDMA RF engineering.

 

At conclusion, participants should be familiar with the key principles of signal physics and interference principles, RF propagation in the wireless environment, antennas for wireless systems, traffic engineering and wireless capacity considerations, as well as the key operational and design issues of CDMA systems.
