Annotation
Code Division Multi-Access (CDMA) is suitable technique for one to multi-point ranging, but it suffers from the Near-Far effect (NFE) i.e. the signal of a farther one will be masked by the nearest one. Unlike the territorial CDMA system aiming at achieving the acceptable lowest Signal to Interference plus Noise ratio (SINR) for a large number of users, the space CDMA ranging system requires higher SINR for a better ranging performance. Consequently, the method of dynamically tracking the Optimal Balanced SINR based on fuzzy logic control is proposed for satellite cluster relative position recognizing.
