It is known that, in general, an AP-frame is an -frame and conversely. Here, in part as a consequence of the Ergodic Theorem, we prove a necessary and sufficient condition for a Gabor system to be an -Frame in terms of Gaussian stationary random processes. In addition, if is a wide sense stationary random process, we study density conditions for the associated stationary sequences .

AP帧和平稳随机过程
众所周知,一般来说,一个 AP 帧是一个-框架,反之亦然。在这里,部分由于遍历定理,我们证明了 Gabor 系统的充分必要条件成为一个-根据高斯平稳随机过程的框架。此外,如果是广义平稳随机过程,我们研究相关平稳序列的密度条件.
