Abstract

In this study, the instantaneous channel capacity of orthogonal frequency division multiplexing (OFDM) transmission with low carrier frequency offset (CFO) over additive white Gaussian noise (AWGN) channels is obtained by taking advantage of the relationship between average bit error rate (ABER) and average channel capacity (ACC) performance metrics. In other words, the channel capacity of OFDM is investigated using bit error rate performance with a novel measurement method. Moreover, the results are extended to the exact ACC analysis over generalized flat fading channels and the cases of Rayleigh and Nakagami-m flat fading environments are investigated. The proposed closed-form expressions are compared with the well-known Gaussian approximation (GA) method to show their advantage and then verified with numerical results.
