| 摘 要： | 基于802．16标准的微波存取全球互通（WiMAX）技术能够提供较高数据速率传输和较高的频谱利用率,并且实现简单,是宽带无线接入系统中最富有竞争力的技术之一。针对WiMAX系统中峰均值功率比（PAPR）过高的问题,从硬件实现的角度出发,利用协调旋转数字计算（CORDIC）算法来求出信号的幅度,采用限幅加滤波的方法来达到降低队PR的目的。实验结果表明这种方法在降低PAPR．值方面具有结构简单,效果良好的特点。

| Abstract: | Worldwide Interoperability for Microwave Access （WiMAX） technology based on 802.16 standard support high data transmission rate and high frequency efficiency. The realization of WiMAX system is not very complicated. It will become one of the most competitive technologies in broadband wireless access systems. This paper introduces a method of dipping and filtering to reduce the value of Peak-to-Average Power Ratio using CORDIC algorithm to calculate the magnitude of OFDM signal from the hardware realization point of view. The result indicates that this method of reducing value of PAPR has simple structure and good performance. |
