The system and the method of improving the signal-noise ratio which lightens CDMA cross correlation arch fact, in TDMA determination network

摘要

The correction system for the time division multiplex access (TDMA) determination system is disclosed. The position receiver pulse the plural mark division multiplex accesses (CDMA) which are forwarded acquires the determination signal which is modulated with time division multiplex access (TDMA) scheme, pursues, and recovers. The specialization correction processor which is the position reception inside of a plane is formed of the plural which is received the time division multiplex access (TDMA) determination signal same period doing, in order each one to form false random number (PRN) cord/code signal replica of the mark divided multiplex access (CDMA) determination signal inside. As for this correlation system, the harmful effect of mark divided multiplex access (CDMA) cross correlation arch fact does not exist, in addition it does not deteriorate signal-noise ratio, therefore position solution of high accuracy the position receiver which gives the range measurement which is made computable is offered.
