Multicarrier CDMA techniques for future wideband wireless networks

摘要

In this paper, multicarrier technique are considered in the context of the future wideband wireless networks. An overview of the different access schemes based on a com- bination of code division and multicarrier techniques, such as Multi-Carrier Code Division Multiple Access(MC- CDMA), Multi-Carrier Direct Sequence CDMA(MC-DS-CDMA) And Multi-tone CDMA(MT-CDMA)is presented first. After- Wards, MC-CDM systems are considered for the downlink Of high rate cellular networks. The performance of diffe- Estimated and then compared with the help of Monte Carlo simulations for a Rayleigh channel.
