【摘要】 循环卷积可通过离散傅里叶变换快速实现,因此具有很高的实际应用价值。本文结合最新的第四代移动通信系统中已成功应用的正交频分复用技术,介绍循环卷积在正交频分复用中的应用,并结合具体实例,使学生能更深刻的理解和掌握循环卷积。既丰富了教学内容,又开阔了学生的知识面,使教学与科研充分结合。更多还原

【Abstract】 The circular convolution can be fast achieved by the discrete Fourier transform(DFT),so it is practical for various applications. This paper introduces the application of circular convolution in orthogonal frequency division multiplexing(OFDM) system which has already been successfully applied in the latest fourth generation mobile communication systems. Provided specific examples,students can deeply understand the circular convolution.The content of this paper fully integrates teaching and scientific research,not only enriching the teaching content,but also widening the horizon of students.更多还原
