Abstract

Bir alici cihaz Doppler yayilmasi kestirimcisi, azalma ve islemden geçirmek için dijital numuneleri sinyallere çevirmekten dolayi zaman içinde degisen bir yayim kanali üzerinden sinyalleri alan bir alici ihtiva eder. Bir duraganlastirici etkin bir sekilde dijital numuneleri alici duraganlastiricisi ile iliskilidir. Bir kestirimci etkin bir sekilde, duraganlastirilmis dijital numunelerin spektral yogunlugunun kestirimi için duraganlastirici ile iliskilidir. Bir iliskilendirici gerçek Doppler yayilmasinin bir kestirimi olarak Doppler yayilmasi degerlerinin birinin seçilmesi için çogul Doppler yayilmasi degerlerinin hipotezlerine karsilik gelen islevler ile spektral yogunluk kestirimlerinin iliskilendirilmesi için etkin bir sekilde kestirimciye baglanmistir.
