AN-808 APPLICATION NOTE

Multicarrier CDMA2000 Feasibility
by Brad Brannon and Bill Schoeld

ABSTRACT The goal of this application note is to determine the feasibility of implementing a multicarrier CDMA2000 transceiver and what the major subsystem performances must be. GENERALIZED BLOCK DIAGRAM The block diagram in Figure 1 is the general block diagram used in this discussion. While there are many variations of this design, the key focus is on this architecture, which represents a exible radio platform that can easily implement a wide variety of air standards including WCDMA, CDMA2000, and TD-SCDMA.

Some variations of this architecture include high or low IF sampling as well a
