                         Space Antenna (LISA) are degraded by the phase fluctuations of the 
                         onboard clocks, resulting in unacceptable sensitivity performance 
                         levels of the interferometric data. The current scheme for 
                         cancellation of the clock phase noise requires 1 GHz modulation of 
                         the ranging laser beams and additional interspacecraft clock 
                         recovery heterodyne phase measurements. Here, we report 
                         experimental results for an alternative approach to clock noise 
                         cancellation based on modified second generation time-delay 
                         interferometry (TDI) with optical frequency combs (OFCs). The use 
                         of OFCs in the LISA scheme allows simultaneous cancellation of 
                         both laser and clock noises, and would eliminate the need for 1 
                         GHz laser modulations and associated demodulation detections. Two 
                         Mach-Zehnder interferometers with acousto-optic modulators were 
                         used to simulate two LISA arms with Doppler shifts and time 
                         delays. With a self-referenced OFC locked to the laser providing 
                         the clock signal, we achieve simultaneous suppression of laser and 
                         clock noises by 7 and 1.5 orders of magnitudes, respectively, down 
                         to the setup noise floor. Based on a numerical analysis, we 
                         further show that the noise suppression performance of the 
                         OFC-based TDI scheme can meet the LISA mission requirements with 
                         an ample margin.",
