Millimeter-wave communication has received considerable attention for use in new-generation broadband wireless communication because of the scarcity of microwave band spectrum resources.The unlicensed frequency band at 60 GHz is suitable for indoor short-range broadband communication.In this paper,we introduce a 60 GHz millimeter-wave short-range wireless communication demo system adhering to the IEEE 802.11ad standard and targeting high-definition video streaming transmission.The system uses single-carrier transmission with frequency-domain equalization.The hardware prototype consists of a 65-nm CMOS radio-frequency front-end and a baseband transceiver for the physical layer functions.Important baseband technologies such as carrier synchronization,phase noise compensation,frequency-domain equalization,and low-density parity-check decoding based on probability calculation are also discussed.The system performance is demonstrated in an experiment on high-definition video transmission,where a data rate of 3.52 Gbps is achieved with a quadrature phase-shift keying signal over a distance of 5.109 m.
