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. en_US DC.subject 長期演進技術 zh_TW DC.subject 正交分頻多工 zh_TW DC.subject 收發機 zh_TW DC.subject 軟體定義無線電 zh_TW DC.subject 寬頻 zh_TW DC.subject LTE en_US DC.subject OFDM en_US DC.subject Transceiver en_US DC.subject Software-Define-Radio en_US DC.subject Wideband en_US DC.title 以軟體定義無線電平台設計與實現 寬頻OFDM收發機 zh_TW dc.language.iso zh-TW zh-TW DC.title Design and Implementation of Wideband OFDM Transceiver with SDR Platform en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
