| Abstract: | OFDM technology has good anti-multipath decline ability,which is very suitable for coal mine tunnel wireless communication.According to the complex and random wireless channel characteristics,this paper establishes a system simulation model under the environment of matlab,based on the simulation and comparison of different channel estimation algorithms,the channel estimation algorithm based on DCT was chosen,and was realized in FPGA hardware platform.The simulation results show that the algorithm is a channel estimation implementation scheme which perform well in the coal mine tunnel wireless channel environment,and the practical value is better. |
