软件无线电技术及其应用探讨

Software Defined Radio Technology and Applied Discussion

软件无线电的出现是无线电通信从模拟到数字、从固定到移动后,由硬件到软件的第三次变革,被认为是继模拟通信技术、数字通信技术之后的第三代无线通信技术。软件无线电以其极强的灵活性和开放性代表着无线通信系统的发展趋势。本文分别从软件无线电技术特点、关键技术、应用等方面分别进行了阐述。

The appearance of Software Defined Radio marks the third transform of the wireless communications from simulation to digital, from immobile to remotion, from hardware to software,it is also consided the third generation wireless communication technology after the simulation communications, digital communications.Software Defined Radio commissary the develop current of wireless communications.In this paper, A brief introduction about its technic specialty, key technology , application investigate is given.
