Title: Philippe Mary: Innovator in Data Transmission and Spectrum Access

Introduction

Philippe Mary is a notable inventor based in Cesson-Sevigne, France. He has made significant contributions to the fields of data transmission and spectrum access, holding two patents that showcase his innovative approaches.

Latest Patents

One of Philippe Mary's latest patents is a method for opportunistic access to the spectrum. This method allows a secondary user to access a frequency band dedicated to a synchronous primary network. The frequency band is divided into K independent channels, each assigned an indicator and an average availability. The method involves observing the channel with the greatest indicator and updating the average availability based on whether the channel is busy or free. If the channel is free, data is transmitted, and a quality index is computed to update the indicators of all channels.

Another significant patent involves a method for transmitting a sequence of data symbols using electromagnetic waves that carry orbital angular momentum. This method includes a bijective selection of an order of orbital angular momentum for each distinct value of a data symbol. The selected order is then transmitted, representing the value of the data symbol effectively.
