Multi-object TT&C technology based on spread-spectrum adaptive feedback filtering algorithm

To the demand of multi-object trace technology in the developing TT&C(tele-tracking & controlling)system,a special algorithm for information code in TT&C system is put forward to solve the problems in multi-object trace system.The algorithm adopts the different coding and decoding way from the spread-spectrum CDMA(code division multiple access)system,it can use the existing TT&C equipment,to solve the task of multi-object trace,and the jam of many users working at the same time by means of the spread-spectrum adaptive feedback filtering algorithm.The elements of new spread-spectrum adaptive feedback filtering algorithm are proposed and the calculating results verify the algorithm's availability.
