Abstract:

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.
