Kablosuz iletişim sistemleri günümüz araştırma ve geliştirme alanlarının en dinamik olanlarından birisidir. Son yıllarda çok popüler olan kablosuz iletişim teknolojilerinden birisi doğrudan dizili kod bölmeli çoklu erişim (DD-KBÇE) sistemidir. Bu çalışmada DD-KBÇE iletişim sistemlerinin bit hata oranı (BHO) başarımları, bina içi ve bina dışı ortamlarda çok yollu yayılıma sahip sönümlemeli kanalların tanımlanabilmesi için önerilmiş uygun bir istatistiksel bir model olan Weibull sönümlü kanallar üzerinden analiz edilmiştir. İletişim sistemlerinin BHO başarımları hem Gold ve Walsh Hadamard kodları gibi iki farklı yayma kodu kullanılarak hem de Weibull sönümlenmeli kanalın sönümleme parametreleri değiştirilerek elde edilmiştir. Farklı kullanıcı sayıları için gerçekleştirilen başarım analizleri sonucunda Walsh Hadamard yayma kodlarının artan kullanıcı sayılarında Gold kodlarından oldukça üstün oldukları görülmüştür.
