介绍了一种基于运动轨迹的插值信道估计方法，把插值问题转化为求解均匀加速运动轨迹问题。相对于其他线性插值及二次插值的插值信道估计方法，该方法具有计算复杂度低，算法简单，可以实时计算等特点。通过仿真表明，在低车速时，该算法的误比特率性与线性插值方法基本相同；而在中高车速时，该算法的误比特率性能要明显优于线性插值信道估计方法，与二次插值信道估计方法的性能基本相同。

A New Interpolation Channel Estimation Method of Movement track

A new interpolation channel estimation method based on movement track is proposed. It puts the interpolation problem convert to seek the uniform acceleration movement track problem. Compared with the linear interpolation and quadratic interpolation channel estimation based on polynomial models, it has the characteristic of low complexity, simple arithmetic and real time computation. Simulation results prove that the performance of the new method is similar with the linear interpolation method at the lower velocity; while it is better than the linear interpolation method at the higher velocity and a little worse than the quadratic polynomial interpolation.
