英文摘要
In Code Division Multiple Access (CDMA), multiple access communication is realized by assigning spreading sequences to each simultaneous signal. In this study, much more efficient spreading sequences are proposed and evaluated in CDMA. In particular, orthogonal chaotic spreading sequences which have good correlation property obtained by brain-style signal processing and complex chaotic sequences with constant power are investigated. On the other hand, a quantity which shows differences in pure random or chaotic sequences is found and evaluated.
