Abstract

Abstract

Adaptive modulation can improve the system performance with high spectral efficiency. In this paper, a combining scheme of MC-CDMA and adaptive modulation is proposed in order to achieve the frequency diversity and the spectral efficiency without loss of much BER performance. The performance of the MC-CDMA system with adaptive modulation is analyzed. Simulation results also indicate the combining schemes and the channel environment will affect the efficiency of adaptive modulation algorithm in MC-CDMA systems.
