DSP를 이용한 DSSS-QPSK 방식의 모뎀에 관한 연구
A study on the Direct Sequence Spread Spectrum QPSK Modem Using DSP
초록
This paper presents the design and implementation of a baseband Modem using DSP that supports a wireless LAN. It is implemented with DSP and D/A and A/D Converters in baseband and tested without using IF and RF modules. In this paper, we have used the matched filler and DLL(delay lock loop) for synchronization. And the matched filter and the carrier recovery are directly connected. Therefore, the proposed architecture is very simple and the operation of DSP becomes fast.
