We discuss the entangled coherent states in symmetry phase space by introducing orthogonal basis, calculate their entanglement by means of concurrence, and investigate their squeezing effects of single-mode and two-mode and antibunching effects. The calculations indicate that the entangled coherent state in symmetry phase space is closely related to nonclassical effect.
