A Novel Adaptive OFO-OFDM Modulation for Visible Light Communication

Öz:

Radio frequency techniques have been deployed in the past time forwireless communication and following its spectral crunch and limited throughput,the visible light spectrum with enormously large bandwidth and potentials forhigh throughput is being investigated in this work. This study is aimed atinvestigating and modeling a signal conditioning scheme in the visible lightspectrum in view of enhancing the throughput of the network. To effectivelyenhance communication throughput, a possible solution is to deploy multicarriertechniques. In this work, an adaptive Optimized Flipped Optical (OFO) OFDM isproposed for improved throughput using Lagrange Multiplier and BroydenFletcher Goldfarb Shanno Algorithm (BFGSA). The Lagrange Multiplier techniquewas used to formulate the model for the optimization of the throughputconstrained by the bit error rate (BER) and the total subcarrier transmit powerwhereas the BFGSA was used for the estimation of the approximation to theHessian matrix for the computation of the optimal throughput value. Resultsshowed improved spectral efficiency in favor of the proposed algorithm whencompared with the conventional schemes. Further validations revealed theperformance superiority of the proposed algorithm when compared with Castel,Wyglinski and Bedeer algorithms under comparable operating conditions for agiven average signal to noise ratio (SNR).

Görünür Işık İletişimi için Yeni Bir Adaptif OFO-OFDM Modülasyonu

Öz:

Radyo frekansı teknikleri Geçmişte kablosuz iletişim için konuşlandırılmış ve spektral sıkıntısını ve sınırlı iş hacmini takiben, son derece büyük bant genişliğine sahip görünür ışık spektrumu ve yüksek verimlilik potansiyeli bu çalışmada araştırılmaktadır. Bu çalışma, ağın verimini artırmak için görünür ışık spektrumunda bir sinyal koşullandırma şemasını araştırmayı ve modellemeyi amaçlamaktadır. İletişim verimini etkili bir şekilde artırmak için olası bir çözüm, çoklu taşıyıcı tekniklerini kullanmaktır. Bu çalışmada, Lagrange Multiplier ve Broyden Fletcher Goldfarb Shanno Algorithm (BFGSA) kullanılarak geliştirilmiş verim için uyarlanabilir bir Optimize Edilmiş Ters Optik (OFO) OFDM önerilmiştir. Lagrange Çarpanı tekniği, bit hata oranı (BER) ve toplam alt taşıyıcı iletim gücü ile sınırlandırılan verimin optimizasyonu için modeli formüle etmek için kullanılırken, BFGSA, aşağıdaki hesaplamalar için Hessian matrisine yaklaşımın tahmini için kullanılmıştır. Sonuçlar, geleneksel şemalarla karşılaştırıldığında önerilen algoritmanın lehine gelişmiş spektral verimlilik gösterdi. Diğer doğrulamalar, belirli bir ortalama sinyal-gürültü oranı (SNR) için karşılaştırılabilir çalışma koşulları altında Castel, Wyglinski ve Bedeer algoritmalarıyla karşılaştırıldığında önerilen algoritmanın performans üstünlüğünü ortaya koydu.
