FPGA Prototyping of A Millimeter-Wave Multiple Gigabit WLAN System

IEEE 802.11aj (45-GHz) standard is recently proposed for wireless local area network operating in an undefined millimeter-wave (mmWave) band. In this work, an ultra-high-speed mmWave orthogonal frequency division multiplexing transmission prototype is developed and some primary amendments in this standard are verified using NI-PXIe mmWave softwaredefined-radio platform. A mixed parallel processing scheme is devised to meet the clock requirements of field programmable gate arrays baseband processing. A queue-based synchronization mechanism is designed to facilitate the implementation of data transporting. Data transmission test indicates that the system is able to achieve an extremely high data rate of multi-gigabits per second with a low bit error rate.
