Analysis of RIS Transmitter Systems Using Dual-Branch Selection Combining Technique with AWGGN

Öz

In this study, error analysis of a reconfigurable intelligence surface assisted dual-branch selection combining communication system with additive white generalized Gaussian noise conditions is investigated. The considered system model is assumed to be in Rayleigh fading channels, and the error analysis is performed based on the probability density function. As a result of the analysis, an approximate error expression was derived and various scenarios were presented with different system parameter values.

Öz

Bu çalışmada, iki kollu seçme birleştirme tekniğini kullanan uyarlanabilir akıllı yüzey destekli bir haberleşme sisteminin eklenebilir beyaz genelleştirilmiş Gauss gürültüsü koşullarında hata analizi incelenmiştir. Ele alınan sistem modelinin Rayleigh sönümlü kanallarda olduğu varsayılmış ve hata analizi olasılık yoğunluk fonksiyonu temel alınarak gerçekleştirilmiştir. Yapılan analiz sonucunda yaklaşık bir hata ifadesi türetilmiş ve farklı sistem parametre değerleri ile çeşitli senaryolar sunulmuştur.
