A novel scheme of photonic aided vector millimeter-wave(mm-wave)signal generation without a digital-to-analog con-verter(DAC)is proposed.Based on our scheme,a 20 Gb/s 4-ary quadrature amplitude modulation(4-QAM)mm-wave signal is generated without using a DAC.The experiment results demonstrate that the bit error rate(BER)of 20 Gb/s 4-QAM mm-wave signal can reach below the hard-decision forward-error-correction threshold after a delivery over 1 m wireless dis-tance.Because the DAC is not required,it can reduce the system cost.Besides,by using photonic technology,the system is easily integrated to create large-scale production and application in high-speed optical communication.

马上就要到清明节和寒食节了。小读者对清明节都很熟悉，但提到寒食节，有人可能就比较陌生了。寒食节在清明节的前一天，其历史可以追溯到2600多年前。歷史上，寒食是一个重大的节日，尤其是唐代，清明和寒食合一假期最长可达6天。唐代诗人韩翃在《寒食》“春城无处不飞花，寒食东风御柳斜。日幕汉宫传蜡烛，轻烟散入五侯家。”可见唐对寒食的重视。 为何“寒食” 寒食节，顾名思义，是一个吃“寒食”的节日。那么，人们
