| Abstract(in English) | This paper presents a stepgain update algorithm for blind adaptive decorrelating detector. The decorrelating detector is a filter which totaly eliminates multiaccess interference when the users signiture sequences are linerly independent. Blind adaptive decorrelating detector(BADD) converges to the one-shot decorrelating detector at asynchronous DS/CDMA channels. BADD requires only desired user's signature sequence and the variance of the additive white Gaussian noise for construction of the receiver for desired user. The proposed algorithm recursively updates the BADD step gain for efficiently converge. The computer simulation show the algorithm can following the increase number of users, by using only same knowledge of BADD. |
