Multicarrier Technologies for 4G Mobile Communications - TRAINING


Course Description

This course will take you to the core of LTE systems, where Orthogonal Frequency Division Multiplexing (OFDM) communication scheme is used.
The course aims to prepare the participant to deal with any of Long Term Evolution (LTE) generation. In addition, the course will discuss the difference and the migration process from UMTS to LTE.
