On the Error Performance of Sectorized Cellular Systems for MC-CDMA and OFDMA

Overview This paper addresses downlink systems based on Orthogonal Frequency Division Multiplexing (OFDM). The systems are situated in a sectorized cellular structure whereas the cellular environment model takes into account path loss and shadowing depending on the position of the mobile terminal. The paper investigates and compares the error performances in such environments of the OFDM based Multiple Access scheme (OFDMA) and the Multi-Carrier Code Division Multiple Access (MC-CDMA) scheme. The performance of an OFDMA system can be enhanced for a lower-loaded system by introducing a Radio Resource Management (RRM).
