This paper presents a high-throughput and highly-reliable 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 147 MHz was fabricated using UMC 0.13 micrometer 1P8M CMOS technology. By adopting the OFDM modulation with 1024 sub-carriers, it achieves a throughput of 820 Mb/s and 10-4 BER performance under 30 dB CNR with 5/6 coding rate. Power dissipation is 189 mW/391 mW (TX/RX).
