Design of channel estimation algorithm inOFDM system based on FPGA

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 code is carried out in the Quartus II software development environment.Finally,EP2C35F672C6 of CycloneⅡ created by ALTERA company was selected as the core hardware platform to design hardware.
