摘要：120 GHz频段近距离无线系统，实现首个10 Gbit/s实时传输，满足极低功耗无线电台法规（ELRS法规）。光子技术的使用使发射机能够执行10 Gbit/s正交相移键控（QPSK）调制，并生成具有可忽略的小杂散信号的RF频谱。发射信号的相位随着外部环境的变化而波动，这干扰了使用参考信号的解调。为了克服发射端的相位波动，我们使用差分相干检测进行解调。我们验证了集成发射器的测量RF频谱水平低于ELRS法规定义的水平。发射器和接收器在10 mm的距离上实现了无差错无线传输，链路裕度为11 dB。关键词：毫米波无线技术，微波光子学，QPSK
Abstract: A 120-GHz-band close-proximity wireless system that achieves the first 10-Gbit/s real-time transmission satisfying the regulation for extremely low-power radio stations (ELRS regulation). The use of photonic technologies enables the transmitter to perform 10-Gbit/s quadrature-phase-shift keying (QPSK) modulation and generate an RF spectrum with negligibly small spurious signals. The phase of the emitted signal fluctuates with changes in the external environment, which interferes with the demodulation using a reference signal. To overcome phase fluctuation at the transmitter, we use differentially coherent detection for the demodulation. We verified that the level of the measured RF spectrum of the integrated transmitter was below the level defined by the ELRS regulation. The transmitter and the receiver demonstrated error-free wireless transmission over a distance of 10 mm with a link margin of 11 dB.
