It is an effective method to use diversity reception in Rayleigh channel.The best performance can be obtained when the diversity signals are independent of each other.The correlation between those signals deteriorates the bit-error performance.There is only an analysis for dual diversity in existing literatures.A theoretic analysis on bit-error performance is given when the diversity branches are more than two and correlative with each other.Especially
in the case of the non-uniform correlation between the diversity branches in practical application
the bit-error performance is analyzed and calculated
and the simulation is completed by use of a computer.Finally
some calculated results are given and plotted into curves for several kinds of typical cases.
