Applications of the Polyphase Filters to Software Radio
Jianzhong Wang · Ordnance Industry Automation · 2004
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.
