2、 paper proposes filter-bank multi-carrier(FBMC)modulation as a promising alternative to PAM4,6,8,12,16 and discrete multi-tone(DMT)for next-generation 400Gb/s+per lane long-reach electrical interconnect.An extensive pathfinding investigation is performed to compare the seven options.PAM6,PAM8,and FB

3、MC are identified as likely candidates,with FBMC showing high resilience to many typical impairments.Moreover,the TX DAC,RX ADC,and DSP design assumptions are only slightly elevated over current 200Gb/s interconnect.Author(s)Biography Jeremy Cosson-Martin received his Ph.D.degree in Electrical Engin
