A scheme of channel estimation based on the pilot filtering
HE Zhong-qiu · Information technology newsletter · 2009
In the typical channel estimation method,pilot is easy affected by the noise and disturbance,so the system performance is going to bad.In order to overcome this problem,a new scheme is proposed,that is using the pilot filtering method both in the time domain and frequency domain.The algorithm is simple and available to realize in the WiMAX system.Under the different models,the results of simulation proved that this scheme can improve the system performance obviously.
