Abstract The adaptive channel weighting estimation method is used for the estimation of the gain in radio transmission channel. It includes: forward equalization for the present time interval to obtain forward adaptive channel estimation value, reverse qualization of the same time interval to obtain reverse adaptive channel estimation value; lattice weighting treatment of the forward adaptive channel estimation value and the reverse adaptive channel estimation value to obtain ultimate channel gain estimation value. The method estimates pilot frequency channel through judging feedback process, tracks data business channel by using coherent detection and adaptive algorithm, and is one scheme combining judging feedback, adaptive linear predication and lattice weighting.
