Performance analysis of single carrier and multicarrier DS-CDMA systems over generalized fading channels

Using a recently developed moment generating function-based approach for the performance evaluation of digital communications over fading channels, we present a unified approach for the exact performance analysis of binary direct-sequence code division multiple access (DS-CDMA) systems operating over generalized frequency-selective fading channels. The results are applicable to single carrier systems employing RAKE reception as well as to multicarrier DS-CDMA systems with frequency diversity. Aside from simplifying previous results both analytically and computationally, the proposed approach also gives a solution for many situations which heretofore defied a simple form.
