满足一定自相关特性的最优测深序列对于基于非迭代测深方法的快速信道估计技术是有用的。我们研究由等量复杂符号组成的最优序列。提出了一种考虑序列符号相位差的间接序列构造方法。我们的构造方法包括周期和非周期最优序列，并提供了基于连续一根相位差序列的最优序列的性质和性质的见解。
Optimal sounding sequences which satisfy a certain autocorrelation property are useful for fast channel estimation techniques which are based on noniterative channel sounding methods. We study optimal sequences consisting of complex symbols with constant magnitude. An indirect sequence construction method is derived by considering the phase difference between sequence symbols. Our construction method includes periodic and nonperiodic optimal sequences, and provides insight into the nature and properties of optimal sequences that are based on consecutive roots-of-unity phase difference sequences.
