Abstract

A new joint detection technique has been considered for application in multicarrier code division multiple access systems. Two basic approaches have been taken into account. One is based on the adaptive algorithms applied in direct sequence CDMA systems. The other one is a new adaptive technique implemented in the so called "time-domain prime". Computational complexity of this new method is discussed, and simulation results are presented
