dc.description.abstract | In this article we describe and evaluate a general class of synchronous multi-carrier CDMA methods. In the proposed methods each accessing user is encoded by a Hadamard sequence and a multi-carrier (MC) encoder. The MC-encoder may provide one or many sub-carriers for each access channel while each accessing user may distribute its transmit power over all sub-carriers of its own access channel or over all sub-carriers of all access channels. Each sub-carrier then carries the transmitted symbols of all users which are distinguished by their Hadamard sequences. In the performance evaluation presented herein we have examined their tolerance to synchronization jitter. © 2005 IEEE. | en |
