Özet

One of the most popular families of time-frequency representations is the t -Wigner transform. This paper is concerned with the boundedness of the t -Wigner transform. Boundedness results for the t -Wigner transform are obtained in both Hardy and BMO spaces. The Hardy and BMO-distance between two t -Wigner transforms associated with different windows and different argument functions are then studied.
