AbstractIn this paper, the modulation technique ESIM- OFDM is analyzed considering a scenario with nonlinear distor- tions from PAs and AWGN channel. In particular, a theoretical expression for the BEP is presented for the scenario under consideration. The theoretical derivation is validated through computational simulations. Moreover, a performance comparison is performed with the classical OFDM. The results showed that ESIM-OFDM has better BEP performance than conventional technique, for the same spectral efficiency, in the scenario with nonlinear PA.
