Chapter 5. CDMA System Range and Capacity Improvement Using Spatial Filtering

In this chapter, analytical tools are developed to study the performance of CDMA cellular radio systems which use spatial filtering, as well as to determine practical limits on the number of simultaneous active users that can be supported in these systems. In later chapters, we discuss spatial signal processing techniques used to implement CDMA spatial filtering. However, before delving into details on how to implement smart antennas for CDMA, it is useful to examine the potential performance improvements expected. Because this is vital for determining system benefits and cost justification for smart antennas, we take several approaches to analyze these systems. First, ...
