We investigate the quantum-classical correspondence of kicked harmonic oscillator (KHO) model by the averaged semiquantum method. Furthermore, we investigate the decoherence of N dimensional kicked harmonic oscillator with different coupling strengths and the dimensionalities. The averaged semiquantum method origins from the time-dependent variational principle (TDVP) formulation and contains nondiagonal matrix elements, so it can be applied to study dissipation, measurement and decoherence problems. When applied to the harmonic oscillator model coupled to a heat bath with different coupling strengths and dimensionalities of the bath, we find that the loss of coherence between superposed wave packets can be also predicted by the averaged semiquantum method.
