摘要 在OFDM系统中,围绕基带预补偿解决功放线性化问题,提出了一种简单可行的盲扫反映射方法。此方法根据功放特性及预补偿原理,通过训练功放特性量化查询表地址并更新补偿值。理论分析及仿真表明此方法节省了硬件资源,提高了预补偿器的补偿能力。 To improve linearization of power amplifier in OFDM systems,this paper proposes a noval blind estimation and re-mapping base-band predistortion methed,Theoretical analysis and is simulation results show that this method has good performance and easy to realize in hardware.
