With the progress of the technologies of wireless communication, 5G system has been continued to thrive and flourished for the better. The data rate and throuthput of IoT (Internet of Things) and IoV (Internet of Vehicle) are vital poins to be considered. Especially with the development of high-speed RF board of RFSoC, the data rate and throughput of 5G system have been attracted more attention. In this research, we select the OFDM modulation system under the LTE DownLink architecture to develop transceiver modules with high-speed and high data rate, and use this demoststratic to modify and pexpand it, finally, to implement it on the FPGA platform.
In hardware, we use verilog hardware description language to conduct design
and implement multiple parallel OFDM transceiver. On platform, we use FPGA (Field Programmable Gate Array) board. The transmitter includes parallel-to-serial processor, constellation mapper, reference signal and frame structure, subcarrier allocation, IFFT processor and cyclic prefix inserter. The receiver includes signal synchronizer (includes symbol synchronizer and subcarrier frequency synchronizer), FFT processor, de-subcarrier allocation, de-frame structure, channel estimator and channel equalizer. |
