Code division multiple access (CDMA) S-ALOHA adalah teknik akses yang menggabungkan CDMA dan S-ALOHA yang memiliki kinerja yang Iebih baik dari elemen pendukung CDMA ataupun S-ALOHA sendiri. Teknik akses CDMA S-ALOHA sangat mendukung integrasi suara, data dan video (multimedia) yang sangat diperlukan untuk komunikasi masa depan. Analisis kinerja bit error rate (BER) CDMA yang biasa dilakukan adalah dengan pendekatan Gaussian (Gaussian Approximation, GA) pada pendekatan ini pengaruh multiple acces interference (MAI) diasumsikan sebagai noise. Untuk ...

This paper will analyze the performance of adaptive slotted ALOHA DS-CDM4 over multipath fading with capture eject to increase throughput transmit data when traffic condition in saturation. To divine intervention we use algorithm to control level change transmission rate use user based on trqffic condition. Adaptive slotted ALOHA DS-CDA/L4 technique is technique access can do adaptation level transmission rate based trams condition. Using protocol access channel adaptive slotted ALOHA DS-CDAM combine between slotted ALOHA and ...

Throughput S-ALOHA CDM4 using technique of diversities MRC differential detected with L branch antenna has been analyzed Desired signal will be intercepted then combined and also analyzed the influence of co channel interference. By using two different model of fading between desired signal and interference signal, throughput can he analyzed under channel condition of Nakagami/ Nakagami and Rician/Nakagami. MRC diversities and differential detection (DPSK) with L branch antenna are used on receiver to overcome multi ...
