软件无线电技术中芯片运算速率的需求

The Demands of the Chip conversion Rate in Software Radio Techniques

随着宽带Ａ／Ｄ／Ａ变换器与ＤＳＰ处理器的发展，软件无线电必将成为移动通信的主流技术。从通信理论角度分析了软件无线电对Ａ／Ｄ／Ａ芯片变换速率及ＤＳＰ处理器芯片处理能力的需求，不难看出，当前的Ａ／Ｄ／Ａ及ＤＳＰ技术水平，只能在基带实施实时信道处理。随着技术发展，在中频或射频实施实时信道处理必将使软件无线电优越性能充分发挥出来。

With the development of broadband A/D/A converter and DSP processor,software radio techniques are going to be the mainstream in the field of mobile communication.Here the requirement,including the speed of the coversion in A/D/A chip and the capacity of the DSP processor are analyzed based on the communication theory.It is not difficult to see that the level of current A/D/A and DSP techniques can only meet the needs of applying it to the baseband real time process.The real time process on intermediate and high frequeney will show the advantage of software radio techniques in the coming future.
