Abstract
A Broadband ATM satellite Experiment (BASE) was carried out between the Communications Research Centre, Canada and Rome Laboratory, USA during the period of May 95 to March 96. The objective of the experiment was to perform a series of tests to characterize broadband ATM satellite bearers. This document reports on the second portion of the first phase of the experiment that was conducted from July 95 to September 95 over the NASA ACTS satellite(Ka-band). Tests consisted in measurement of ATM Quality of Service (QoS) parameters such as Cell Loss Ratio (CLR) and Cell Error Ratio (CER) as a function of Bit Error Rate (BER). In this report, results are presented for two different modulations (QPSK and 8-PSK) and compared against theoretical curves. Results show that Ku- and Ka-band satellite channels have similar ATM behaviour. Results suggest that applications using ATM over burst error channel will experience greater difficulties for a given bit error rate than they would for a random error media. The characterization of the breaking point remains, however, application dependent. Moreover, the broadband channel and its embeeded sub-channels have been found to be coherent. As suggest in (1) and now confirmed, this result implies that the characteristics of the sub-channels can be inferred from the broadband channel and vice-versa.
