Abstract :
Architecture of a cross-coupled decision feedback detector is suggested to reduce both inter-symbol-interference and multiple-access interference for an asynchronous multicarrier CDMA scheme for the reverse link of a mobile communication system. Results show that an enhancement in capacity and good interference resistance are obtained.
