基于FPGA的基带OFDM系统的方案设计

The Design of OFDM Systems Based on FPGA

DSP,ASIC,FPGA芯片的迅速发展和广泛的应用,促进了OFDM系统的发展。一个好的OFDM系统需要大量的数据处理,如信道编码、同步技术等。早在20世纪50年代提出的OFDM技术,直到近几年才逐步成熟并被使用,这与高速数字信号处理芯片的发展也有密切的关系。提出了实现基带OFDM系统的方法——FPGA方案。

The rapid development and the widespread application of DSP, ASIC and FPGA chips have promoted the development of OFDM system. An excellent OFDM system needs a great amount of data processing, e.g. channel coding, and synchronous technology, etc. In the early 50s of 20th century, OFDM technology was put forward and it becomes matured and employed till the recent years, which has a close relation with the development of the chips of high-speed digital signal processors. This paper introduces the method for realizing OFDM systems on baseband： FPGA program.
