- Abstract
- In this paper, multicarrier code division multiple access (MC-CDMA) system based on the discrete cosine transform (DCT) and the discrete sine transform (DST) is proposed and investigated. The resulting systems are denoted by DCT-MC-CDMA and DST-MC-CDMA. DCT and DST use only real arithmetics rather than the complex arithmetics used in the discrete Fourier transform (DFT). This reduces signal processing complexity, and the in-phase/quadrature imbalance. The bit error rate (BER) performances of the DCT-MC-CDMA and the DST-MC-CDMA systems are studied and compared with that of the DFT-based MC-CDMA (DFT-MC-CDMA) system. Simulation results show that the proposed systems provide better BER performance than that of the conventional DFT-MC-CDMA system, while the complexities of the receivers are slightly increased.
