Abstract
Radyo frekansı (RF) dijital alıcı sisteminin (1), saptama kararlarının bir spektral tahmine (9) dayanarak alındığı durumda ayrık Fourier dönüşüm (DFT) aracı (7) kullandığı bir radyo frekansı dijital alıcı sistemi ve yöntemi tarif edilir. Spektral tahmin (9), DFT aracının (7) bir çıktısından oluşturulur; burada spektral tahmin (9), aracın, mekansal olarak varyant apodizasyon (SVA) (13) sağlamak için dahil edilmesiyle geliştirilir; böylelikle RF dijital alıcının saptama kabiliyeti geliştirilir. Buluşun bir başka düzeneğinde SVA (13), Dijital Sinyal İşleme (DSP) ile kullanım için optimize edilir.
