Abstract

In the conventional multipath-decorrelating receiver, the complexity and noise enhancement increase with the number of resolvable paths. In this paper, we propose a scheme that adaptively selects a subset of the paths reducing both system complexity and noise enhancement. We provide analytical results that show the tradeoff between noise enhancement and multipath induced multiple access interference for better performance.

Özet

Bilinen çokyollu tersilişkileyici alıcılarda, sistemin karmaşıklığı ve meydana gelen gürültü artırımı kanalın çözülebilir yollarının sayısına bağımlı olarak artar. Bu çalışmada, kanal katsayılarından yararlanıp sistemin başarım sonuçlarına çok fazla etki etmeyen düşük enerjili yolların alıcıda kullanılmaması yoluna gidilerek hem sistemin karmaşıklığını hem de gürültü artırımını azaltacak bir yapı üzerinde durulmuştur. Gürültü artırımı ve kullanılmayan yollardan dolayı meydana gelen çoklu erişim kaybı arasındaki ilişki analitik formüllerle verilmiş ve sistemin başarımındaki artış gösterilmiştir.
