研究了信号f∈L1[0,1]的广义沃尔什级数的收敛性质.我们还展示了广义沃尔什基对N×N酉矩阵的依赖性如何允许在信号编码和加密中的应用,只要信号在[0,1]的N-adic子区间上是分段常数。
We investigate convergence properties of generalized Walsh series associated with signals f∈L1[0,1]. We also show how the dependence of the generalized Walsh bases on N×N unitary matrices allows for applications in signal encoding and encryption, provided the signals are piece-wise constant on N-adic subintervals of [0,1].
