Abstract This paper derives a novel asymptotic bit error rate (BER) expression for dual-carrier modulation (DCM) over Nakagami-m fading channels at high signal-to-noise ratio (SNR). Through this analysis, the achievable modulation gain and diversity order are provided, and the relative SNR gain that occurs when the channel environments of two distantly paired sub-carriers differ is also evaluated. Numerical results demonstrate that the derived expressions accurately predict the asymptotic behavior at high SNR across various fading scenarios. These findings offer valuable insights for optimizing DCM implementations in practical wireless communication environments.
