Introduction to the UTRA FDD Radio Interface

In this chapter, we will give a simple – but vital – introduction to the UTRA FDD radio interface, so the reader can easily follow and comprehend later sections of the book. We will start with some general CDMA-based principles, which are then followed by a description of the UTRA physical channels and a discussion of some key mechanisms that are used in the UTRA FDD system. The chapter concludes with a brief description of those parameters that we consider to be of most importance in the network optimisation process.
