Abstract :
OFDM is an important technology in the high-speed date transmission. The channel estimation is the key technology in the OFDM system. In this paper, the OFDM system is mainly introduced. The channel estimation technology based on the comb- pilot is deeply studied. Through the simulation the different interpolation algorithms based on the comb-pilot are deeply compared. At last we get the important conclusion.
