ABSTRACT
This paper analyzes the performance of the adaptive fu-
sion method for macroscopic diversity combination in the
wireless cellular environment when the error probability in-
formation from each base station detection is not available.
The performance analysis includes the derivation of the min-
imum achievable error probability. An alternative realiza-
tion with lower complexity of the optimal fusion scheme
by using selection diversity is also proposed. The selection
of the information bit in this realization is obtained either
from the most reliable base station or through the majority
rule from the participating base stations. The performance
comparison in Rayleigh fading and log-normal shadowing
