Abstract

The need for flexible network structures has created a successful Wireless Local Area Network (WLAN) market, promising to replace many wired LANs in the near future. The latest draft of IEEE 802.11n offers the potential of throughputs beyond 200 Mbps, based on physical layer data rates up to 600 Mbps. IEEE 802.11n standard adopts low density parity check coding as optional coding scheme to offer higher reliability in PHY level. LDPC may end up as the standard scheme in a host of sectors including communications, broadcasting and even hard disk drives. This paper presents LDPC efficient encoder and decoder then the performance of LDPC based on IEEE 802.11n standard is studied. Different modulation and coding schemes were compared to get the best choice.
