现代通信系统的许多应用中都在寻求具有高线性复杂度和低相关函数值的伪随机二进制序列。构建了一个新的伪随机二进制序列族，即级联 GMW 序列。这些序列与 B. Gordon、W.A. Mills 和 L.R. 的 GMW 序列共享许多理想的相关特性。 Welch (1962)——例如，高位移自相关值，并且在许多情况下，具有 m 序列的三值互相关值。此外，结果表明，在许多情况下，级联 GMW 序列的线性复杂度远远大于 GMW 序列的线性复杂度。 >
Pseudorandom binary sequences with high linear complexity and low correlation function values are sought in many applications of modern communication systems. A new family of pseudorandom binary sequences, cascaded GMW sequences, is constructed. These sequences are shown to share many desirable correlation properties with the GMW sequences of B. Gordon, W.A. Mills, and L.R. Welch (1962)-for example, high-shifted autocorrelation values and, in many cases, three-valued cross-correlation values with m-sequences. It is shown, moreover, that in many cases the linear complexities of cascaded GMW sequences are far greater than those of GMW sequences. >
