Abstract

In this paper, we present an analytical approach to study the power estimate of the interference in a MC-CDMA transmission scheme. The receiver is implementing a simple RAKE architecture that is not near-far resistant. The regenerated signal (RS) technique is applied on a symbol basis for power estimation of the jamming signal. An exact equation of this estimate is obtained for L uncorrelated diversity branches, and the impact of diversity order is discussed.
