Abstract :
This paper presents an implementation of IEEE802.11a wireless LAN system including a baseband processor and MAC (medium access control). We introduce some innovative techniques improving the performance as well as to fulfill the mandatory requirement of the standard. The evaluation system consists of a test-board with the fabricated base band processor chip and an ARM-base SoC platform for implementing MAC. The baseband processor was fabricated using MagnaChip 0.25 mum CMOS technology, occupying size of 5 mm times 5 mm. The demonstration of WLAN system was successfully donewith various wireless environments AWGN, multi-path Rayleigh fading and Rician one.
