| Abstract: |
| The design and implementation of PHS cell station signal reconstruction device based on ML7338 is introduced,the hardware and software design and compiling are given,and the software flow is explained in detail.The ML7338(ARM7TDMI core) and RF module RDA5206 are used to demodulate RF signals,recode,remodulate and transmit baseband signals,thus solving the RF interference problem in traditional stations. The device implements the storage and transfer of PHS signals,and effectively solves the problem of blind spot on PHS network. |
