摘要 (Abstract): 

The time delay interferometry (TDI) is an algorithm proposed to suppress the laser frequency noise in spaceborne gravitational wave detectors. In this paper, the geometric TDI is utilized to investigate the modified second-generation TDI combinations in conjunction with a ternary search algorithm. For the sixteen-link combinations, forty second-generation TDI solutions are recovered, among which nine of them are identified as the modified second-generation ones. Furthermore, we explore the properties of the modified second-generation TDI solutions. It is argued that the modified second-generation TDI solutions present a quantitative advantage over their second-generation counterparts. Moreover, analytic analysis confirms that the alternative modified second-generation TDI solutions are desirable in accordance with previous findings.
