Web1 de abr. de 2024 · O FDM faz uso da faixa de proteção, enquanto o OFDM eliminou o uso da faixa de proteção. A eficiência espectral do OFDM é melhor que o FDM. O FDM é facilmente afetado por outros recursos de RF, tornando-o vulnerável a interferências. Por outro lado, o OFDM não é afetado por interferências. Web18 de jul. de 2024 · 4 Simulation results. An indoor environment for ACO-OFDM-NOMA in VLC is designed, which has a dimension of 5 m\times 5 m\times 3 m. The parameters for simulation of above VLC model is mentioned in Table 1. Here a single LED is used to transmit the data for two user placed at distance of 0.5 m and 3 m.
