Disclosed are a joint sparse channel estimation method, device and system. The method comprises: building a joint sparse reconstruction model, merging all channels to be estimated into a joint sparse vector, solving the positions of all nonzero element blocks of the joint sparse vector by means of the joint sparse reconstruction model, and solving values of nonzero elements of the channels. By means of the present invention, the channel estimation accuracy can be improved, and the pilot overhead can be reduced. |
