Wideband generalized multicarrier CDMA over frequency-selective wireless channels

Relying on symbol blocking and judicious design of user codes, this paper builds on a Generalized Multicarrier (GMC) quasi-synchronous CDMA system capable of multiuser interference (MUI) elimination and intersymbol interference (ISI) suppression with guaranteed symbol recovery, regardless of the wireless frequency selective channels. GMC-CDMA provides a unifying framework for multicarrier (MC) CDMA systems and o ers exibility in full load (maximum number of users allowed by the available bandwidth) as well in reduced load settings. Analytic evaluation and simulations illustrate that GMC-CDMA outperforms competing MC-CDMA alternatives especially in the presence of uplink multipath channels.
