Kurs Titel:

WCDMA FDD Physical Layer and Procedures

   

Bestell-Nr.:

TA-TC 1740

   

Dauer:

3 days / web session 3x4 hours

   

Zielgruppe:

WCDMA FDD planners, radio optimization engineers, personal concerned with performance measurements.

   

Zielsetzung:

The course describes the physical layer of the WCDMA FDD mode including the latest HSPA+ features. The radio transmission (modulation, scrambling and spreading) with all relevant physical channels as well as the physical layer procedures (cell search, random access, dedicated channel synchronization, adaptive modulation and coding, fast re-transmission, power control, handover etc.) are explained in detail.
