Bilinmeyen haberleşme sinyallerinin gözü kapalı
ve işbirliksiz tanınması için geliştirilen teknikler, hem askeri hem de sivil uygulamalarda kullanım bulmuştur. Çok Girdili Çok Çıktılı (MIMO) haberleşme sistemleri, sinyal tanıma sistemleri için üstesinden gelinmesi gereken yeni problemler ortaya koymaktadır. MIMO haberleşmesinde kullanılan uzay zaman kodlarının gözükapalı tanınması bu problemlerin en önemlilerinden biri olarak görülebilir. Bu çalışmada uzay zaman blok kodlanmış sinyal vektörlerinin döngüsel-durağan (cyclostationary) karakteristiklerinin farklı uzay zaman blok kodlarını birbirinden ayırdetmek amacıyla kullanıldığı yenilikçi uzay-zaman kodu tanıma algoritmaları öneriyoruz. Signal identification techniques developed for the purpose of blind and noncooperative identification of the transmission parameters of unknown communication signals have been employed both in military and civilian applications. Blind identification of the Space-Time Block Codes (STBC) used in a multiantenna transmisson can be regarded as one of the new and most significant challenges presented to the signal identification systems by the Multiple-Input-Multiple-Output (MIMO) transmission systems. In this work, we present novel STBC classification algorithms that exploit the cyclostationary characteristics of the coded transmit signals as discriminating features.
