The carrier super-positioning satellite system is a promising telecommunication system because the frequency efficiency is double that of existing satellite systems. In this technique, we use the same frequency band for inbound and outbound signals that is currently used in separated bands. So, we need to cancel the undesired signal and pick up the desired signal from the received signal to implement this system. Our research group has proposed some methods for signal canceling over the last several years. This time, we focus on a distance measuring method for a signal canceller using multi-component code (MCC) and validate its precision for distance measuring. We evaluated the usability of MCC in the case in which actually modulated signal is added to MCC with higher power than MCC. According to the results of simulation and theoretical validation, the longer the time required for distance measurement, the smaller the error probability of the calculation for measurement. And it is observed that the MCC method works well in the actual environment of satellite networks that suffer from severe interference and level variation.
