Title: The Innovations of Roberto Montagna
Introduction
Roberto Montagna is a notable inventor based in Turin, Italy. He has made significant contributions to the field of telecommunications, particularly in the area of speech signal coding. With a total of 6 patents to his name, Montagna's work has had a lasting impact on how speech signals are processed and transmitted.
Latest Patents
Montagna's latest patents include a "Method of and device for coding speech signals." This invention involves subdividing the set of possible excitation signals into multiple subsets. The first subset provides the necessary contribution to the coded signal for transmission at a minimum guaranteed rate. The other subsets contribute to increasing the rate in successive steps. At the receiving end, a decoded signal is generated using only the first subset if the coded signals are received at the minimum rate. For higher rates, contributions from the additional subsets are also utilized.
Another significant patent is the "System for embedded coding of speech signals," which shares a similar methodology. The first subset again ensures the minimum transmission rate, while the other subsets allow for rate increases. This innovative approach enhances the efficiency of speech signal transmission.
