Abstract
A windowing unit (WFU) improves band-limited noise immunity of a fourier transformer (FT) of which it is a part. The windowing unit (WFU) comprises a digital window filter (WI) and a folding processor (F). The window function (W) of the digital window filter (WI) consists of a window head (HEAD), a window body (BODY), and a window tail (TAIL), and the shape of the window function (W) is chosen so that the window head (HEAD) is complementary to a tail (BODY TAIL) of a window body (BODY), and similarly the window tail (TAIL) is complementary to a head (BODY HEAD) of the window body (BODY). The folding processor (F) performs the task of mapping the information received in the window head (HEAD) on to the tail (BODY TAIL) of the window body (BODY) and mapping the information received in the window tail (TAIL) on to the head (BODY HEAD) of the window body (BODY).
