| 摘 要： | 软件无线电采样有射频低通、射频直接带通和宽带中频带通三种.求出多相滤波器频率响应后,用多个基于相同原型滤波器的数字滤波器将其划分为多个信道输出以达到降低信道输出速率的目的.通过改变抽取或内插位置来降低数字滤波器的处理速度,实现信号实时处理.数字信道化接收机是基于多相滤波的软件无线电的典型应用. |
| 关 键 词： | 多相滤波 软件无线电 输出速率 |

| Abstract: | The sampling method for software radio, which include RF low pass sampling, RF pass band direct sampling and Broad Band IF pass band sampling. After polyphase filter frequency response was done, the channel out rate was fallen, and it was divided into multi-channel by the several digital filters based on the same archetype filter. The process speed of digital filter was fallen by change sequence of interpolator to realize real time process. Digital channelized receiver is a typical application of software radio based on polyphase filters. |
