我们提出了一种用于安全通信和干扰抑制的新型收发器，可在 10GHz 左右的大带宽上运行。具体来说，提出了一种结合频率和代码复用的新颖编码方法。同样重要的是通过波束成形实施低功耗现场编码来降低功耗和硬件。后者将数字化仪的功耗要求降低了 8 至 32 倍。在本文中，我们描述了所提出的高数据系统和集成编码方案。还会在存在干扰的情况下评估系统性能，并进行噪声分析以评估编码对不同本底噪声的影响。初步结果显示，使用理想滤波器和 5 位最小数字化仪分辨率的正交 Walsh-Hadamard 码的退化最小。
We propose a new class of transceivers for secure communication and interference mitigation, operating over large bandwidths on the order of 10GHz. Specifically, a novel coding approach that combines frequency and code multiplexing is proposed. Equally important is power and hardware reduction by implementing a low power on-site coding with beamforming. The latter reduces power requirements for the digitizer by a factor of 8 to 32. In this paper, we present a description of the proposed high data system and integrated coding scheme. System performance is also evaluated in presence of interference and noise analysis is conducted to assess the impact of coding for different noise floors. Preliminary results show minimal degradation using orthogonal Walsh-Hadamard codes using ideal filters and a minimum digitizer resolution of 5 bits.
