Bu çalışma beşinci nesil (5G) iletişim sistemleri için aday olan iletim tekniklerinin bit hata oranı (BHO) başarımlarını araştırmaktadır. Performans analizleri 5G araştırmaları için önerilmiş kanal modellerinden birisi olan A tipi Dallı Gecikme Hattı kanal modeli göz önünde bulundurularak gerçekleştirilmiştir. Analizler gerçekleştirilirken detaylı incelemelerin gerçekleştirilebilmesi için hem sabit alıcı/verici birimler hem de hareketli alıcı/verici birimlerin olduğu durumlar dikkate alınmıştır. Ayrıca kanal gecikme yayılımının farklı profilleri de değerlendirilerek analiz senaryoları genişletilmiştir. Elde edilen performans sonuçları hareketli ve yüksek gecikme yayılımına sahip kanal durumunda Filtre Bankası Çoklu Taşıyıcı (Filtered Bank Multiple Carrier, FBMC) iletim tekniğini kullanan iletişim sistemlerinin daha iyi bir performansa sahip olduğunu ve bu sistemin diğer sistemlere göre daha kararlı davrandığını göstermiştir.

BIT ERROR RATE PERFORMANCE INVESTIGATION OF CANDIDATE TRANSMISSION TECHNIQUES FOR 5G COMMUNICATION SYSTEMS

Öz

This paper examines bit error rate (BER) performances of transmission techniques that are candidates for fifth-generation (5G) communication systems. Performance analyses are performed by considering Tapped Delay Line (TDL-A) which is a channel model proposed for the 5G studies. In order to provide comprehensive analysis, both stationary transmitter/receiver units and active receiver/transmitter units are taken into account while performing the analyses. In addition, analysis scenarios are expanded by evaluating different delay spread profiles. The obtained results show that the communications systems utilizing Filtered Bank Multiple Carrier (FBMC) transmission technique provides better performance and it operates more reliable than that of other candidates in case of active units and channel conditions with high delay spread.
