|
| () |
| Abstract: |
| This paper discusses the design method of the RFID reader based on DSP technology.On the basis of the description of the RFID system structure,the reader's software and hardware design flow are given.Using DSP software to process the received signal and the realization method of anti-collision function are emphatically expounded.The reader has been applied in the open gate system,and the result of practical application proves its good performance. |
| Key words: radio frequency identification(RFID),digital signal processor,finite impulse response filter,anti-collision,open gate system |
