| Abstract: | Based on the channel coherence time and noise accumulation property, the optimal pilot interval design rule is presented. Simulations are done over the ITU-VA channel at different vehicle speeds, and the results prove that the proposed design rule is reasonable and the experiential value for the optimal pilot interval is also given from lots of simulation results. |
