Publisher’s description

In this paper, two candidates for a next generation (4G) downlink system in a multi-cell environment are studied in respect to their error performance. The paper investigates on the one hand, an Orthogonal Frequency Division Multiplexing (OFDM) based Multiple Access scheme (OFDMA), and on the other hand, a Multi-Carrier Code Division Multiple Access (MC-CDMA) scheme. The studies of both transmission schemes are done in a cellular structure. To enhance the performance of OFDMA, a Radio Resource Management (RRM) is introduced.
