This dissertation has as main objective to present the implementation of an ADSL software-modem totally written in Java, using the Ptolemy II framework, named Hermes (from \A Handy Experimental softwaRe ModEm System"). A software-modem is useful in cases where one needs to perform tests and simulations of communication systems with a large number of modems and when systems' parameters must be changed with high degree of freedom. Besides, a software-modem has features that make it easy to add, eliminate,
validate and evaluate signal processing and telecommunications functions and algorithms. Tests and simulations were performed to evaluate the Hermes functionality, including the use of Tracespan, a non-intrusive analisys equipment for DSL networks. From obtained results together with Tracespan, it was possible to successfully validate the Hermes functions. |
