| Descripción: | This paper first gave a brief introduction of communication channel models, and then describes the characteristics of the channel emulator. According to the characteristics of the channel model, multipath is a difficult problem for hardware implementation. In order to simplify the hardware, the polyphase filter can be used for multi-path delay.Then the paper reviews the polyphase filter in the decimation and interpolation application, and simply introduces the multi-rate system. And then through the simulation experiments, the characteristics of the sub-filter of the polyphase filter were analyzed. Finally, according to the characteristics of the sub-filter, this paper presents an application in multipath delay. |
