We investigate nonclassical properties of the optical field when photon subtraction and addition coherent operation t (a) over cap -F (a) over cap (+) acts on an odd superpositions of coherent states (SCSs) by examining its sub-Poissonian statistics, quadrature squeezing, and negativity of the Wigner WF). It is found that these nonclassical properties can be all significantly enhanced for the output state when the coherent operation is applied to an odd SCSs. Moreover, the results show that the nonclassicality of the coherent operation of SCSs (COSCSs) is sensitive to the coherent operation and amplitude.
