Chapter 7 Physical and Logical Channels of IS-95 CDMA
7.1 Introduction
This chapter first covers how to introduce a CDMA carrier in an existing AMPS or TDMA system, establishing the number of AMPS or TDMA channels that should be removed in order to introduce the first and second CDMA carrier of 1.23 MHz without interfering with the remaining AMPS or TDMA carriers. After this, we briefly describe modulation schemes, bit repetition, block interleaving, and channel coding that are used in processing logical channels on the IS-95 CDMA forward and reverse links. Details about information processing, message types, and message framing are then presented for the pilot, sync, paging, and traffic channels on the forward link. This chapter also provides ...
