摘要
在研究OFDM系统和自适应分配技术的基础上,对几种重要的自适应分配算法进行详细分析,并通过仿真比较了它们的性能和复杂度。仿真结果表明,使用自适应分配算法的OFDM系统可以减小发射功率,提高系统性能。
Based on the study of OFDM system and adaptive allocation technology, some important adaptive algorithms and compares their performances and complexity through this paper analyzes simulations. Simulation results show that with the adaptive allocation algorithm, the transmission power can be significantly reduced and the system performance can be improved at the same time.
