Abstract

The analysis of the envelope correlation coefficient for logarithmic diversity receivers, given by de Neumann [B. de Neumann, “Envelope correlation coefficient for logarithmic diversity receivers,” Electron. Lett., vol. 25, pp. 459–460, Mar. 1989] for one Rayleigh fading branch in isotropic scattering environments (two independent real Gaussian branches), is extended in this letter to the general case where a maximum ratio combiner (MRC) operates on M ≥ 1 independent Rayleigh fading branches, with the same temporal correlation coefficient, in nonisotropic scattering environments. The derived exact closed-form expressions include the results by B. de Neumann in 1989 as special cases. In addition, when M is not so small, theoretical analysis and Monte Carlo simulations show that the envelope correlation coefficient can be accurately approximated by the squared amplitude of the channel correlation coefficient. © 2007 IEEE
