We present several protocols for joint remote state preparation of a single(two)-quadbit state with real (or complex) coefficients via a projective or positive operator-valued measure.In our schemes,three(five)-quadbit non-maximally entangled state(s) have been employed as the quantum channel and several appropriate mutually orthogonal basis are delicately constructed.Finally,the present schemes are extended to the (N + M) senders case.
