A three-and an(N+1)-party dense coding scheme in the case of non-symmetric Hilbert spaces of the particles of a quantum channel are investigated by using a multipartite entangled state.In the ease of the(N+1)-party dense coding scheme,we show that the amount of classical information transmitted from N senders to one receiver is improved.
