论文摘要
在这一贡献中，已经开发了为每个用户（DL）非正交多访问（NOMA）系统中每个用户分配的功率比例的优化。连续的干扰取消（SIC）技术恢复了用户的信号，并在通道获得之间具有较高的差异，以便找到所有活动用户的最低最佳功率比例{保证所需的}同等数据速率。遵循相同的方法，以设计目标获得了每个用户的最佳功率比例以及所有用户获得相同速率（最大公平性）相同速率的最低功率。此外，开发了相同的设计方法，以寻求最大化Noma系统能源效率（EE）。可以找到{最大EE点}和用户之间的各个电路分配，以进行特定电路功耗。对于所有对EE最大化的最佳操作点的NOMA用户，可以找到总功率，功率比和相等的速率值。结果，可以找到每个系统场景的EE和总和率之间的权衡点，以及最佳的资源效率操作点。通过考虑所有用户的相同速率，该系统在用户之间达到了最大的公平性。
In this contribution, the optimization of power proportion allocated for each user in the downlink (DL) non-orthogonal multiple access (NOMA) systems have been developed. Successive interference cancellation (SIC) technique recovers users' signal with high difference between channel gains, in order to find the lowest optimum power proportion {required to guarantee} an equal data rate for all active users. Following the same approach, the optimum power proportion for each user and also the minimum total power to achieve the same rate for all users (maximum fairness) were obtained as a design goal. Moreover, the same design methodology was developed seeking to maximize the NOMA system energy efficiency (EE). It was possible to find the {maximum EE point} and the respective power distribution among the users for a certain circuitry power consumption. For all NOMA users in which the optimal operation point for EE maximization was parameterized, it was possible to find the total power, power ratio and the equal rate values. As a result, one can find the tradeoff point between EE and sum rate for each system scenario, as well as the best resource efficiency operation point. By considering the same rate for all users, the system attains maximum fairness among the users.
