In this Letter, we propose the application of delta-sigma modulation (DSM) higher-order quadrature amplitude modulation (QAM) technology in long-distance transmission of W-band wireless communication, and demonstrate, for the first time to the best of our knowledge, the wireless transmission of millimeter wave signals in the W-band based on 1-bit DSM quantization using polarization-division-multiplexed orthogonal frequency division multiplexing (PDM-OFDM) 1024QAM/4096QAM for 4.6 km. We successfully achieved a bit error rate (BER) of 40-Gbit/s PDM-OFDM 1024QAM and 48-Gbit/s PDM-OFDM 4096QAM after 4.6-km wireless transmission, both lower than the soft decision forward error correction (SD-FEC) of 4.2 × 10. To the best of our knowledge, this is the first time that up to 4096QAM signals have been quantized and transmitted based on 1-bit DSM in a 4.6-km-long distance W-band millimeter wave system.
在本信函中，我们提出将三角积分调制（DSM）高阶正交幅度调制（QAM）技术应用于W波段无线通信的长距离传输，并据我们所知首次展示了基于1比特DSM量化、采用偏振复用正交频分复用（PDM-OFDM）1024QAM/4096QAM在W波段进行毫米波信号4.6千米的无线传输。在4.6千米无线传输后，我们成功实现了40吉比特/秒PDM-OFDM 1024QAM和48吉比特/秒PDM-OFDM 4096QAM的误码率，均低于4.2×10的软判决前向纠错（SD-FEC）。据我们所知，这是首次在4.6千米长距离W波段毫米波系统中基于1比特DSM对高达4096QAM信号进行量化和传输。
