WebSep 22, 2024 · It is a modulation process that allows digital data to be transmitted in a multi-path channel while ensuring a good compromise between performance and spectral occupancy. This technique will be dealt with in part two. In the third and last part, we will implement the CE-OFDM technique in the THz context.
WebJul 15, 2024 · The main reason is their vulnerability to nonlinear distortions. In this paper we propose a novel multi-carrier technique, called Constant-Envelope Single-Carrier FDMA (CE-SC-FDMA). In this technique, a nonlinear phase modulation is applied to an SC-FDMA signal rather than to an OFDM signal, as proposed by prior state-of-the-art contributions.
