我们考虑由Wilson基引起的类型的展开式。我们刻画了L2(λ)的这种扩张。作为一个应用程序,我们看到,这样的扩展必须是正交的,在相反的情况下,由平移和膨胀产生的小波展开。
We consider expansions of the type arising from Wilson bases. We characterize such expansions for L2(ℝ). As an application, we see that such an expansion must be orthonormal, in contrast to the case of wavelet expansions generated by translations and dilation.
