    摘要: This paper focuses on the research of channel capacity of multiple-input multipleoutput
    (MIMO) system with different transmitting angles in straight and curvy tunnels.Araytracing
    technique is developed to calculate channel frequency responses for tunnels, and the
    channel frequency response is further used to calculate corresponding channel capacity. The
    channel capacities are calculated based on the realistic environment. The channel capacities
    of MIMO long term evolution system using spatial and polar antenna arrays by different
    transmitting angles are computed. Numerical results show that, The channel capacity for
    transmitting angle at 15◦ is largest compared to the other angles in the tunnels. Moreover,
    the channel capacity of polar array is better than that of spatial array both in the straight and
    curvy tunnels. Besides, the channel capacity for the tunnels with traffic is larger than that
    without traffic. Finally, it isworth noting that in these cases the presentwork provides not only
    comparative information but also quantitative information on the performance reduction.
