Abstract :
Channel estimation is a key technology in wireless communication field, and estimation method based on pilot is one of the most common methods. To improve the performance of Channel estimation in OFDM system, different estimation algorithms are studied and an improved interpolation algorithm is proposed. The simulation results show that the improved interpolation algorithm can effective against spectrum leakage and has much lower BER.
