Abstract

This paper describes the crest-factor analysis of carrier interferometry MC-CDMA and OFDM systems. The maximum crest factor of CF signals grows as log(N). Thus there appears to be an impressive reduction in the crest factor of CI signals. The crest factor performance for carrier interferometry systems is the same as in standard systems, in the sense that the statistical distributions of CF are identical. Hence, the carrier interferometry approach has no CF gain in the asymptotic regime. This analysis is advantageous in terms of BER and diversity.
