Multicarrier CDMA

Multicarrier code-division multiple-access (MC-CDMA) can simultaneously combat frequency selective fading and multiple-access interference (MAI) by combining the advantages of multicarrier modulation and CDMA. Since fading and MAI are the two major difficulties in wireless communications, MC-CDMA is a promising technology for wireless multimedia communications. Other advantages of MC-CDMA include flexibility for supporting multirate traffics with different QoS requirements and transmitter optimization to reduce power consumption. The main objective of this project is to investigate the use of MC-CDMA in wireless multimedia systems.
