TABLE OF CONTENTS In FDMA and TDMA systems, traffic channels are allocated to calls as long as they are available. Incoming calls are blocked when all channels have been assigned.
The physical parallel in CDMA systems is for a call to arrive and find that the BS has no receiver processors left to serve it [1]. In a CDMA system, the CE in each BS corresponds to the receiver processor and performs the baseband spread spectrum signal processing of a received signal for a given channel (pilot, sync, paging, or traffic channel). Practically, CDMA systems are equipped with a finite number of CEs with a cost-efficient strategy because CEs are a cost part of BSs, which introduce inherent hard blocking in CDMA systems. However, often a more stringent limit on the number of simultaneous users in a CDMA system is the total interference created by the admitted users, and its measurement is the outage, which occurs when the interference level reaches a predetermined value above the background noise level. In this situation, a call attempt in CDMA systems can be blocked not only by the maximum number of supportable users in the air link but also by the maximum number of CEs available in BS, and the Erlang capacity will be confined by these two resource limits.
In this book, we tackle the Erlang capacity evaluation of CDMA systems with following two cases: the first one is that there is a finite number of CEs in a BS, and the second...
