Abstract :
The combination of code division multiple access (CDMA) and multicarrier (MC) transmission techniques, termed MC-CDMA, is considered a promising alternative to conventional DS (direct sequence)-CDMA. An MC-CDMA concept which is well-suited for mobile radio applications is described. This concept overcomes the disadvantages of previously proposed concepts. In MC-CDMA mobile radio systems, signal reception is impaired by time-varying multipath propagation. The impairments can be reduced by coherent receiver antenna diversity (CRAD). The application of CRAD in combination with joint detection (JD) techniques to the more critical uplink of MC-CDMA mobile radio systems is investigated. Four JD techniques for CRAD are presented and their performance are studied
