Abstract

We have experimentally demonstrated, for the first time, photonics-aided J-band 7.48-Gb/s QPSK signals and 2.5-Gb/s 512-QAM signals using delta-sigma modulation over 1.2-km wireless link. After 1.2-km wireless transmission, the bit error rate (BER) of the 512-QAM is below the 20% soft decision forward error correction (SD-FEC) threshold of 2 × 10⁻². As far as we know, this is the longest distance achieved for wireless transmission in a photonics-aided J-band wireless transmission system.

在 220 千兆赫频率下使用三角Σ调制技术无线传输 512-QAM 信号 1.2 千米

我们首次在 1.2 千米的无线链路上实验性地演示了使用三角Σ调制的光子辅助 J 波段 7.48-Gb/s QPSK 信号和 2.5-Gb/s 512-QAM 信号。经过 1.2 千米的无线传输后，512-QAM 的误码率（BER）低于 20% 的软决策前向纠错（SD-FEC）阈值 2 × 10-2。据我们所知，这是光子辅助 J 波段无线传输系统实现的最远距离无线传输。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
