Spektrum algılamada amaç spektrum boşluklarının doğru ve hızlı bir şekilde algılanmasıdır. Bu nedenle bilişsel radyo ağlarının başarımı büyük ölçüde spektrum algılama işlevine bağlıdır. Bu çalışmada, bilişsel radyo ağlarında spektrum algılma başarımını artırmak için çevrimiçi öğrenme tabanlı işbirlikçi spektrum algılama algoritması önerilmiştir. Önerilen yöntemin işbirlikçi spektrum algılama başarım analizi sönümsüz AWGN kanala ilaveten Rayleigh, Nakagami-m ve Rician sönümlü kanallarında yapılmıştır. Simülasyon çalışmaları sonucunda, bilişsel radyo ağlarında geçmiş verilerden eşik değer ifadesinin optimize edilmesi ve işbirlikçi algılama yaklaşımı ile daha etkin bir algılama yapılabileceği gösterilmiştir.
