무선 LAN 시스템에서 FHSS을 위한 직접형 디지틀 주파수 합성기에 대한 연구
Study of the Direct Digital Frequency Synthesizer for FHSS in Wireless LAN Systems
초록
The demands of WLAN(Wireless Local Area Network) systems increase rapidly in whole society and this phenonenon has been expected that WLAN wi11 substitute for wired-LAN. The FHSS(Frequency Hopped Spread Spectrum) method using the WLAN is changed to the performance of Frequency synthesizer. In this paper, we proposed pipeline-accumulator using ring-counter method instead of constant accumulator that has demerits of size and power consumption. Designed DDFS generated operating frequency of 167MHz and maximum output frequency of 83.5MHz.
