| Popis: | 91 In recent years, OFDM has become a key technology in the development of new wireless communication systems. It can increase the bandwidth efficiency by utilizing the Fast Fourier Transform as it’s modulator and uses guard interval to combat the inter symbol interference caused by multipath fading. In this thesis, we will realize the MIMO-OFDM baseband transceiver on the Aptix MP3C reconfigurable system platform, which integrates FPGA, DSP and some analog devices. FPGA is a programmable logic device which can be used to design digital logic circuits by hardware description language and provide fast hardware verification based on its reconfigurability. On the other hand, DSP is a powerful processor with high speed floating-point or fixed-point operations, which is suitable for real-time signal processing. In this thesis, we will focus on the realization of MIMO-OFDM transceiver by FPGA, which includes a coarse time synchronizer, a fine time synchronizer, a Discrete Fourier Transform circuit and an auto frequency controller. Together these form the synchronization part of the system. With the concept of software-defined radio incorporated, we can increase the scalability and adaptivity of the system by modulizing the above mentioned hardware circuits. |
