Turbo multiuser detection for MC-CDMA signals with strongly nonlinear transmitters [PDF]
, 2007 In this paper we consider the uplink transmission in MC-CDMA (multicarrier -coded division multiple access) systems. Since MC-CDMA signals are OFDM-like multicarrier signals, they have high envelope fluctuations and a high PMEPR (Peak-to-Mean Envelope ...

Joint turbo equalization and multiuser detection of MC-CDMA signals with low envelope fluctuations [PDF]
, 2008 In this paper, we consider the uplink transmission in multicarrier code-division multiple-access (MC-CDMA) systems. As other multicarrier signals, MC-CDMA signals have high envelope fluctuations and a high peak-to-mean envelope power ratio (PMEPR), which
