We investigate the tensor and the scalar perturbations in the symmetric bouncing universe driven by one ordinary field and its Lee-Wick partner field which is a ghost .
We obtain the even- and the odd-mode functions of the tensor perturbation in the matter-dominated regime .
The tensor perturbation grows in time during the contracting phase of the Universe , and decays during the expanding phase .
The power spectrum for the tensor perturbation is evaluated and the spectral index is given by n _ { T } = 6 .
We add the analysis on the scalar perturbation by inspecting the even- and the odd-mode functions in the matter-dominated regime , which was studied numerically in our previous work .
We conclude that the comoving curvature by the scalar perturbation is constant in the super-horizon scale and starts to decay in the far sub-horizon scale while the Universe expands .
