- Simulation results show effectiveness of the proposed scheme and demonstrate superiority of using the equispaced-grouped pilot sequences. 仿真结果表明了所提算法在时变环境下的有效性和采用等间隔分组导频序列的优越性。
- It is shown that the optimal pilot sequence consists of some adjacent equipowered and equispaced subsequences, and each of them is constrained by certain phase conditions. 可以证明，最优的导频序列是由一些相邻的等间隔等能量的子序列构成，每个子序列的导频之间满足一定的相位关系。
