60-Ghz OFDM Systems for Multi-Gigabit Wireless LAN Applications

This paper presents the developed 60-GHz OFDM hardware demonstrators and the newly designed 60-GHz system architecture targeting for multi-gigabit wireless LAN applications. The hardware demonstrators developed so far are made up of maximum 1-Gbps OFDM baseband realized on FPGA platform and 60-GHz super-heterodyne transceivers fabricated by SiGe BiCMOS technologies. Wireless transmission in 60-GHz links is successfully demonstrated in indoor office environments. The next generation 60-GHz OFDM systems are designed to provide data rate higher than 3-Gbps utilizing the channel bandwidth of 2.16-GHz. Advanced channel coding schemes including low-density-parity-check (LDPC) coding are applied to have higher coding gain. RF transceivers are based on sliding IF architecture and designed to be compatible to the channel plans defined in the 60-GHz standards.
