Abstract

This paper studies the area of link adaptation for multicarrier code division multiple access (MC-CDMA) radio interface and adapts the rate and transmission power jointly over temporal as well as spectral domains. on one side, frequency domain spreading lends a high degree of frequency diversity to MC-CDMA. On the other, it has been identified as the main hurdle when it comes to spectral domain rate allocation in MC-CDMA. This paper presents band based MC-CDMA (BB-MC-CDMA) architecture as an efficient scheme to practically realize the spectral domain rate allocation in MC-CDMA, without undergoing the drawbacks of other published techniques for this purpose. BB-MC-CDMA asks for the elimination of frequency interleaving, usually considered to be an essential ingredient of MC-CDMA. It also suggests an intelligent reduction in the spreading factor in a channel aware fashion. Furthermore, based on BB-MC-CDMA architecture, joint rate and power adaptation over time and frequency (JRPATF) has been shown to outperform the frequency domain power allocation only.
