design rules for cellular networks are not directly applicable
to code division multiple access (CDMA) networks where intercell
interference is not mitigated by cell placement and careful
frequency planning. For transmission quality requirements, a
minimum signal-to-interface ratio (SIR) must be achieved. The
base-station location, its pilot-signal power (which determines
the size of the cell), and the transmission power of the mobiles
all affect the received SIR. In addition, because of the need
for power control in CDMA networks, large cells can cause a lot
of interference to adjacent small cells, posing another
constraint to design. In order to maximize the network capacity
associated with a design, the authors develop a methodology to
calculate the sensitivity of capacity to base-station location,
pilot-signal power, and transmission power of each mobile. To
alleviate the problem caused by d
