中文摘要：
通过对xMax技术指标的分析，阐述了实现xMax的方法．在此基础上提出了一种能实现xMax的类正弦波调制技术．该调制技术通过对类正弦波信号的单周期调制，实现信号对信息的携带，且能达到xMax主带宽窄、边带功率谱密度低、发射功率低、传输速率高等性能指标．通过理论分析和仿真验证，该调制技术功率谱主峰值带宽为300kHz；边带功率谱密度比峰值功率谱低40dB，使边带能很好地隐藏在背景噪声中；传输速率达到7．5Mbit／s．
英文摘要：
Through the specification analysis of xMax technique, a realization method of xMax is elaborated. On this basis, a new method to realize the xMax by the way of sine-like wave modulation is proposed, This modulation technique realizes the information carrying through the method of single cyclical modulation to a kind of sine-like wave signal. The technique can achieve the xMax requirements of narrow bandwidth, low sideband power spectral density, extremely low emissive power and high transmission speed. Analysis and simulation show that the bandwidth of peak power spectrum is 300 kHz, the sideband power spectral density is 40 dB lower than peak value of power spectrum density, which enables the sideband to be able to hide well in the background noise; and transmission speed may be achieved to 7.5 Mbit/s.
