基于软件无线电收发机前端设计方法的分析与研究

Analysis and Research the Front-end Design Method of Software Radio Transceiver

软件无线电技术将很大程度上解决当前个人无线通信系统所面临的挑战如产品开发周期和生存期的挑战,移动终端功能多样化带来的系统集成和功耗的挑战。因而其被提出后很快成为国内外无线通信领域的研究热点,被普遍认为是继无线技术数字化之后的第二次技术革命。通过研究自适应电路设计方法,使软件无线电收发前端的性能可以随着信道质量的变化自适应地调整,从而使电路功耗最小。

Software radio technology will largely address the challenges of the current personal wireless communication system fac-es. Such as product development cycle and survival challenges,and mobile terminal functional diversity brings system integrationand power challenges. The software radio technology was made soon after become a hot topic at home and abroad in the field ofwireless communications, and it is generally regarded digital wireless technology after second technological revolution.By studyingthe adaptive circuit design that enables performance radio front-end software can change the channel with the quality of adaptivelyadjusted to minimize the power consumption of the circuit.
