Abstract
Recently conventional Multi-carrier Code Division Multiple Access (MC-CDMA) techniques attract more attention of researcher’s due to its high frequency spectrum efficiency and high data rate transmission. The aim of this work is to investigate the performance of multi-carrier code division multiple access (MC-CDMA) technique, which is a key technology for efficient and reliable communication due to its high frequency spectrum efficiency and high data rate transmission. This paper presents the performance of conventional MC-CDMA system, orthogonal wavelet packet based MC-CDMA system (WP-MC-CDMA), and Huang Hilbert Transformation (HHT) based MC-CDMA system. This scheme outperforms other two techniques, because this scheme is based on the knowledge of the instantaneous channel state information, or based on instantaneous imperfect channel estimates. Thus, by the knowledge of their channel gains or channel information, it can analyze the data more accurately. Hence, it is a more spectral efficient and high data rate transmission scheme compared to the conventional MC-CDMA and WP-MC-CDMA..
