In this Letter, to further understand the role of nonlinear dispersion in coupled nonlinear wave systems in both real and complex fields, we study the coupled Klein-Gordon equations with nonlinear dispersion in real field (called CKG(m, n, k) equation) and (2 + 1)-dimensional generalization of coupled nonlinear Schrodinger equation with nonlinear dispersion in complex field (called GCNLS(m, n, k) equation) via some transformations. As a consequence, some types of solutions are obtained, which contain compactons, solitary pattern solutions, envelope compacton solutions, envelope solitary pattern solutions, solitary wave solutions and rational solutions.
