摘要:

在这封信中,无线发射机使用的可编程元表面的新架构。所提出的发射机不需要任何滤波器,也不需要宽带混频器或宽带功率放大器,从而使其成为未来具有成本效益的无线通信系统的有前途的硬件架构。使用实验结果,我们证明了一个可编程的元表面为基础的8相移键控(8PSK)发射机与8*32相位可调单元可以实现6.144 Mbps的数据速率在空中在4.25 GHz的误比特率(BER)的性能与传统的方法没有信道编码,但具有更低的硬件复杂度。

英文摘要:

In this letter, a wireless transmitter using the new architecture of programmable metasurface is presented. The proposed transmitter does not require any filter, nor wideband mixer or wideband power amplifier, thereby making it a promising hardware architecture for cost-effective wireless communications systems in the future. Using experimental results, we demonstrate that a programmable metasurface-based 8-phase shift-keying (8PSK) transmitter with 8*32 phase adjustable unit cells can achieve 6.144 Mbps data rate over the air at 4.25 GHz with a comparable bit error rate (BER) performance as the conventional approach without channel coding, but with less hardware complexity.
