| Abstract: | Adaptive modulation and power allocation is introduced into the multicarrier DS-CDMA system to improve the system performance and bandwidth efficiency. First, the system design appropriate for adaptive modulation and power allocation is given, then the algorithm of adaptive modulation and power allocation is applied. Simulation results demonstrate great performance improvement compared with the fixed modulated one. |
