Title: Innovations of Pierre Combelles
Introduction
Pierre Combelles is a notable inventor based in Rennes, France. He has made significant contributions to the field of signal processing, holding a total of 5 patents. His work focuses on developing advanced methods for multicarrier signal modulation, which are crucial for improving communication systems.
Latest Patents
One of his latest patents is titled "Distributed pilot multicarrier signal designed to limit interference affecting said pilots." This invention involves a multicarrier signal that includes a temporal succession of symbols formed by a set of data elements. Each data element modulates a carrier frequency of the signal, which includes reference elements known as pilots. The value of these pilots is known to at least one receiver designed to receive the signal, while the informative data elements have values that are not known a priori. The invention imposes constraints on the informative data elements to reduce interference affecting the pilots during reception.
Another significant patent by Combelles is "Multicarrier modulation using weighted prototype functions." This method involves obtaining a set of 2M representative complex coefficients of transmitted data. The process includes calculating 2LM linear combinations to leave 2M obtained complex coefficients. Coefficients of balancing used in these combinations represent a prototype function. The coefficients are summed in designated memory areas, which represent groups of distinct partial sums. The transmitted samples are sent to gradually form samples for transmission over a defined duration.
