J. Mar et Hy. Chen, PERFORMANCE ANALYSIS OF CELLULAR CDMA NETWORKS OVER FREQUENCY-SELECTIVE FADING CHANNEL, IEEE transactions on vehicular technology, 47(4), 1998, pp. 1234-1244
An effect of multipath fading on the performance of a cellular code-di
vision multiple-access (CDMA) system is analyzed in this paper. A,Fide
-sense stationary uncorrelated scattering (WSSUS) channel model and th
e coherent binary phase-shift keying (BPSK) with asynchronous direct-s
equence (DS) spreading signal are assumed in the analysis. The average
error probability for both the forward link and reverse link of a cel
lular CDMA system over a frequency-selective fading channel using a co
nventional correlation-type receiver and RAKE receiver are derived. Th
e impact of imperfect power control and channel capacity of a cellular
CDMA system is also investigated. The closed forms of average error p
robability derived in the paper can save a lot of computation time to
analyze the performance and channel capacity of a cellular CDMA system
. The analytical results show that the performance and maximum transmi
ssion rate of cellular CDMA system degrade with an increase in the num
ber of simultaneous users and the number of interfering cells. The sig
nal-to-interference ratio (SIR) for reverse link derived in this paper
can directly describe the interrelationships among a number of paths,
number of users, number of interfering cells, fading factors, and max
imum variation of a received unfaded signal.
