本文首先从时域分析的角度推导了空时分组码单载波多天线信道估计对最优训练序列的要求。然后证明了最优性要求与Z-周期互补的概念有关，所需的最优训练序列实际上是一类Z-周期互补序列，它包含了传统的周期互补序列和L-完全序列作为特例.给出了Z-周期互补二元序列及其配对序列的定义和构造方法。
In this paper, the requirement on optimal training sequences for single-carrier multi-antenna channel estimation with space-time block-coding is firstly derived based on time-domain analysis. It is then shown that the optimality requirement relates to a new concept called Z-periodic complementarity, and the desired optimal training sequences are in fact a class of Z-periodic complementary sequences which include the conventional periodic complementary sequences and L-perfect sequences as special cases. Definitions and constructions of the Z-periodic complementary binary sequences and their mates are given.
