A technique for reducing the PMEPR of MC-CDMA signals [PDF]
, 2004 In this paper we consider the use of MCCDMA (Multi-Carrier Code Division Multiple Access) schemes with a frequency-domain orthogonal spreading. The transmitter structure is especially modified for reducing the envelope fluctuations of the transmitted

Timing Synchronization for Mc-Cdma Systems Using a Time-Multiplexed Synchronization Channel
ASEAN Journal on Science and Technology for Development, 2017 In this paper, we present a synchronization algorithm for Multi-Carrier CDMA (MC-CDMA) systems using a time-multiplexed synchronization channel. The simulations results show that a system using proposed algorithm has much higher timing detection ...
