This paper is devoted to the evaluation of probability distribution of multiple access interference in asynchronous Direct Sequence Code Division Multiple Access (DS CDMA) communication system based on chaotic spreading sequences. Statistical properties of such interference in a system with K users causing multiple-access interference obtained by computer simulation are presented. Simulation is carried out for the spreading sequences produced by the logistic map; the length of sequences: N = 7, 31, 63 and the number of users correspondingly: K = (3, 8, 11); (11, 32, 65); (64, 129). Ill. 3, bibl. 8, tabl. 2 (in English; abstracts in English and Russian).
