摘要
在研究能加倍提高数据传输速率的混合调制技术基础上,提出了可重构多用户超宽带射频信号产生方案,灵活地产生一至四阶的高斯导数型的超宽带射频信号,该信号波长稳定、可调范围大、频率啁啾较低、色散容忍度高,无色散补偿情况下在单模光纤中传输75km后波形失真很小。
Based on study the mixed modulation technology which can double the data transfer rate, this paper proposed a signal generation scheme of reconfigurable multi-user ultra-wideband RF, which can flexibly produces a fourth order derivative of Gaussian type UWB RF signal, and the signal has stability wavelength, adjustable range, low frequency chirp, highly chromatic dispersion tolerance.In the absence of dispersion com- pensation,waveform distortion of the signal is small after 75km transmissioninsingle-mode fiber.
