尽管3G无线设备仍在部署中，但整个无线生态系统却已开始定义和设计4G系统。向4G网络的转变给无线通信带来新期待。4G网络的更快速度和分组传输将使高质量多媒体无处不在。实现这种高水准服务的关键就是新的无线接口OFDMA。 尽管3G无线设备仍在部署中 ...

正交频分多址Orthogonal Frequency Division Multiple Access，英文缩写即为OFDMA。需要说明的是，OFDMA是OFDM技术的演进。在利用OFDM对信道进行子载波化后在部分子载波上加载传输数据的传输技术。 目前，OFDMA已被广泛研究，并已成为3GPP LTE的下行链路的主流多址方案。

OFDMA技术作为Wi-Fi6的核心技术之一，为实现更快、更智能的Wi-Fi提供了强大支持。OFDMA技术通过将信道划分为多个RU，允许多个用户在同一时隙内共享信道资源，从而显著提高了频谱利用率、降低了延迟、支持更多用户并发，并提升了服务质量。OFDMA技术在高密度 ...
