Abstract
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 offers flexibility 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.
