In this work, we propose a simple scheme of bidirectional teleportation for transferring unknown coherent superposition states. It consists of exchanging two states by using tripartite entangled coherent states between two parts. This proposed scheme is essentially based on optical devices like beam splitters, phase shifters and photon number measurement detectors. The probability of success and the mean fidelity of quantum teleportation in the presence of quantum noise are evaluated. However, the quantum Fisher information is studied to estimate some parameters such as the weight and the phase of sent states.
