基于FPGA的OFDM系统信道估计算法的设计

Design of channel estimation algorithm inOFDM system based on FPGA

研究了OFDM系统信道估计算法的FPGA实现。首先探讨OFDM系统及其信道估计算法,然后采用VHDL硬件描述语言对OFDM系统中的发送端和接收端的各个模块进行实现,在接收端利用基于导频的信道估计算法得出发送端的数据,并且在Quartus II软件开发环境下对VHDL代码进行波形仿真与综合验证,最后选用以ALTERA公司生产的Cyclone II系列的EP2C35F672C6为核心的硬件平台上进行硬件设计。

This paper studied the FPGA realization of channel estimation algorithm for OFDM system. First it discussed OFDM channel estimation algorithm, and then used VHDL hardware description language to realize the sending and receiving ends of each module in OFDM＇ system. At the receiving end the pilot-based channel estimation algorithm was used to obtained the sending end data. Moreover waveform simulation and integrated authentication to the VHDL cede is carried out in the Quartus II software development environment. Finally, EP2C35F672C6 of Cyclone IT created by ALTERA company was selected as the core hardware platform to design hardware.
