摘要：
A new methodology for closed-form theoretical performance analysis of randomly-spread CDMA systems over multipath fading channels with multiuser receivers is presented. The basis of the analysis is the representation of the random signal to interference ratios at finite system parameters in terms of the eigenvalues of crosscorrelation matrices for which the non-asymptotic average densities are found or known, The methodology presented complements the asymptotic Ruining theory used in similar previous work over Gaussian/singlepath fading channels, but at finite system parameters and over multipath fading channels. One application of the method is demonstrated by spectral efficiency derivations with linear multiuser receivers.
