论文摘要
通过对频谱的交易覆盖率和硬件复杂性，Sub-Thz移动访问网络有望在高指令和相对较低效率低下的传输方面运行，同时仍然可以比当前6GHz的替代方案提供巨大的能力增长。在此假设的基础上，本研究在160 GHz处得到了广泛的室内定向通道测量，主张使用非常简单的调制和均衡技术来进行Sub-Thz移动访问。具体而言，我们证明，在上述传输制度下，得分显着的增益目标几乎不需要或没有均衡。特别是，我们表明，单载波或低音携带者的调制是非常有吸引力的竞争对手，对更加复杂和能量效率低下的传统多载波设计非常有吸引力。
By trading coverage and hardware complexity for abundance of spectrum, sub-THz mobile access networks are expected to operate under highly directive and relatively spectrally inefficient transmission regimes, while still offering enormous capacity gains over current sub-6GHz alternatives. Building on this assumption, and supported by extensive indoor directional channel measurements at 160 GHz, this study advocates the use of very simple modulation and equalization techniques for sub-THz mobile access. Specifically, we demonstrate that, under the aforementioned transmission regimes, little or no equalization is needed for scoring significant capacity gain targets. In particular, we show that single-carrier or low-number-of-subcarriers modulations are very attractive competitors to the dramatically more complex and energy inefficient traditional multi-carrier designs.
