外文摘要：We propose a photonic frequency-multiplied vector millimeter-wave[mmW]signal generation scheme based on constant-envelope delta-sigma modulation[CE-DSM].The CE characteristic of phase modulation can easily avoid intensity-dependent nonlinear distortion caused by photonic frequency multiplication.Additionally,combined with one-bit DSM,the in-band signal-to-noise ratio can be dramatically improved,enabling high-order quadrature amplitude modulation[QAM]vector mmW signal generation with high spectral efficiency.Experimental results indicate that a 40 GHz four-fold frequency-multi-plied 4096-QAM vector mmW signal generation system is successfully accomplished with 15-km standard single-mode fiber[SSMF]and 1-m wireless transmission,and the bit error ratio[BER]reaches the threshold of 3.8 × 10-3.
