| Abstract: |
| This paper discusses the signal detection of IJF-OQPSK,which uses Second order and third order Butterworth filter as detection filter.The results show that the circuit of IJF-OQPSK is not only simple but also has better performance.It can be used in many communication system,specially frequency division system. |
