该文定义了一种离散相关信号,即第1类最佳屏蔽二进序列偶,研究了其性质,证明了第1类最佳屏蔽二进序列偶和伪随机Hadamard矩阵的相互构造性,给出了它们的变换性质。在此基础上,该文提出了一种将第1类最佳屏蔽二进序列偶应用于OFDM信道估计的方案,仿真结果表明,与m序列方式相比,该方法在兼顾系统开销和计算复杂度的情况下,表现出更好的系统性能。

In this paper, a new discrete correlation signal is defined, which can be called as First Kind of Perfect Punctured Binary Sequence Pair （FK-PPBSP）. The properties of FK-PPBSP are studied. The mutual construction between FK-PPBSP and pseudorandom Hadamard matrices is proved. A FK-PPBSP based time-domain channel estimation algorithm for orthogonal frequency division multiplexing （OFDM） is proposed. Simulation results show that compared with m sequence method, a better system performance with lower overhead and lower computational complexity is obtained with the proposed method.
