| Abstract(in English) | The CNR variation characteristics after the diversity combining (the maximal-ratio combining) under Rayleigh fading environments can be evaluated by use of the eigenvalues of the covariance matrix for branch signals. However, this technique was available only when the eigenvalues had different values each other. In this report, we proposed a calculation method for deriving the cumulative distribution function of the CNR when the eigenvalues are composed of multiple groups; the eigenvalues in each group had the same value. It was confirmed that the cdf's obtained by the proposed method and the numerical simulation agreed very well. The accuracy of the calculation results was also discussed. |
