Abstract

Closed-form expressions for energy detector performance parameters are derived using approximations of the central and non-central chi-square distributions. New equations are also presented that minimize the total error rate to obtain the optimal detection threshold. The approaches used have high closeness to the original functions. The analytical results match the results of the simulation for awide range of SNR values.
