Abstract

This paper presents a high-throughput and highlyreliable baseband processor LSI based on LDPC coding OFDM UWB. This LSI targets for wireless LAN systems inside a car which enable to translate a high-resolution video under noisy environment. A chip capable of operating at 147MHz was fabricated using UMC 0.13μm 1P8M CMOS technology. By adopting the OFDM modulation with 1024 sub-carriers, it achieves a throughput of 820Mb/s and 10-4 BER performance under 30dB CNR with 5/6 coding rate. Power dissipation is 189mW/391mW (TX/RX).
