Performance analysis of ATM transmission over a DS-CDMA channel

摘要

This paper presents numerical results for ATM cel transmission over a DS-CDMA satellite link obtained by mathermatical analysis.We show that an increase in capcity cna be achieved by using discontinuous transmission detection (DTX) for all ON-OFF sources.Thus exploiting the burstiness of ATM traffic.Three scenarios are analysed depending on whether the code is allocated to a user or to a single virtual connection (VC),and wheter the transmission rate for different connections is the same or varies across the systme.System performance is experessed in terms of link efficiency and relative capacity increase.Initial results show how different transmission rates and loads affect the system performance.
