Abstract
The unprecedented growth of data traffic driven by mobile applications has accelerated communication technology development. In fact, many mobile applications that require large amount of data transmission have been widely used in our daily lives. The fifth-generation (5G) mobile network infrastructure construction works are in full swing worldwide recently. One of the significant trends that drive 5G network is the high bandwidth to fulfill requirements for plentiful, faster, and content-rich services. In order to meet the performance criteria, the millimeter-wave (mmWave) has been emphasized as an essential technology in 5G technology named as 5G new radio (5G-NR), which will come slighter later. Most of the advanced commercialized 5G networks and devices are implemented at the 3.5 GHz frequency band that can not offer much higher bandwidth than the existing 4G network. Simultaneously, many technique difficulties also limited the 5G-NR network implementation, such as signal coverage, reliability of connection, etc. This thesis presents extensive works based on the 60GHzmmWave communication system. It provides an alternative solution to set a low cost, high bandwidth wireless link at the unlicensed 60GHz mmWave band. It can achieve Gigabits-per-second (Gbps) data rate, point to point light of sight (LoS) communication up to 1-kilometer. The work includes radio frequency (RF) system research, wireless link budget, on-site RF measurement, field programmable gate array (FPGA) based baseband design, realtime operation system (RTOS) based medium access control (MAC) layer design, and embedded Linux based user interface design. The work demonstrated a long-distance 60 GHz wireless communication system with RF, baseband, and MAC layer. It is implemented on the mmWave system-onchip (SoC) transceiver chipset and an FPGA evaluation board with an external Analog to Digital Converter (ADC) / Analog to Digital Converter (DAC) daughter card. The FPGA platform has a dual-core ARM7 microprocessor that works as a baseband and MACprocessor. The proposed design achieves one Gigabits-per-second data rate in the full-duplex mode under quadrature amplitude modulation (QAM) modulation mode.
