| Résumé | Recently, Non-Orthogonal Multiple Access (NOMA) has attracted a major attention and has been seen as a promising technique to handle next generation 5G requirements. In this paper, the application of NOMA in a Vehicle-to-Infrastructure system (V2I) is investigated. Usually, NOMA allocates a greater amount of power to the user in worst propagation conditions in order to improve spectral efficiency and user fairness. In this work, a power allocation scheme based on vehicles mobility is proposed. The system is evaluated based on BER (Bit Error Rate) and spectral efficiency metrics. Rayleigh distribution is utilized to model small scale fading in addition of path loss. Simulations results show that NOMA is a promising technique able to improve spectral efficiency and transmission quality even in a severe propagation conditions as in the case of vehicular networks. The power allocation scheme which takes into consideration nodes mobility show a better performance than the conventional scheme with fixed power allocation. |
