| Abstract(in English) | Lebesgue Spectrum Filter (LSF) is a kind of auto-correlation regulatory filter that makes spreading codes to have exponential decaying auto-correlation profiles, like Markovian codes, which reduces multiple access interference (MAI) of asynchronous DS-CDMA systems. In this study, we extend the auto-correlation parameter of LSF to complex values and propose a system with heterogeneous auto-correlation profiles. Unlike real-valued systems, complex-valued heterogeneous systems show equally MAI suppression for all users and have effect even in sychronous DS-CDMA systems. |
