ACCORD Broadband ATM Satellite Experiment (BASE)-DS3 Ku-band channel

摘要

A Broadband ATM satellite Experiment (BASE) was carried out between theCommunications 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 first portion of the first phase of the experiment that was conducted in May 95 over the AnikE satellite (ku-band). Tests consisted in measurements 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 good agreement with theory when PLCP framing is not mapped into DS-3 frames. The sub-channels have been found to be coherent with respect to each other. Experimental data further suggest that the broadband channel characteristics are similar to its embedded sub-channels. This implies that the characteristics of the sub-channels could be inferred from the broadband channel or that sub-channels results could be extrapolated to broadband channel results.
