Abstract(in English) | In this paper, we describe Frequency Division CDMA system in which the available frequency spectrum units corresponding to the symbol duration are grouped into mutually interference-free sets. Each of the sets consists of the minimum number of such spectrum units as independently fading and assuring frequency diversity effect. Each set of each of the groups is dynamically assigned to several users and the assignments are cyclically shifted to the adjacent sets. We discuss the methods to design the signals for the frequency division CDMA and simmultaneously to estimate multiple access user's channel characteristics using Kalman filter in the frequency selective fading channels and the performance was evaluates by computer simulations. |
