Multitone-Hopping CDMA Using Feedback-Controlled Hopping Pattern for Decentralized Multiple Access CHIBA, Kazuki HAMAMURA, Masanori Copyright © 2008 The Institute of Electronics, Information and Communication Engineers CDMA decentralized asynchronous multipath feedback multitone We propose multitone-hopping code-division multiple access (MH-CDMA) using a feedback-controlled hopping pattern (FCHP) (FCHP/MH-CDMA). In the FCHP/MH-CDMA, part of the filter coefficients of an adaptive finite-duration impulse response (FIR) filter receiver are fed back to a transmitter, in which they are used as an updated hopping pattern. Each chip of the updated hopping pattern consists of plural tones. As a result, it is shown that the FCHP/MH-CDMA provides us with an excellent asynchronous, decentralized multiple-access performance over time-invariant multipath channels.
