| 摘 要： | 为了降低OFDM系统的PAPR,针对传统算法有损系统性能的缺点,提出了一种优化的算法。该算法基于频谱优化和交织思想,通过确定有效子载波个数来提高OFDM符号的平均功率和系统的频谱效率,并通过预判断,选择性地对OFDM符号进行交织处理。仿真结果表明,该算法在降低OFDM的PAPR的同时,也优化了系统的性能。

| Abstract: | Concerning that the main drawback of traditional algorithm,an optimization algorithm was given to reduction PAPR in OFDM system.The algorithm heightened average power and frequency efficiency by computed optimization sub-band number.From the prejudgement,the algorithm disposed OFDM signs by interleaver selectively.Simulation results show that the algorithm can reduce the PAPR and improve capability of OFDM system. |
