  • Automatic gain control system for multi-user digital OFDM transmission systems over the electric network
    Patent number: 7545733
    Abstract: The system includes a plurality of user kits and a head-end kit in bi-directional communication over the electricity network. Its essential characteristics are: carrier by carrier treatment of transmission and reception signals and control of transmission power in each kit. The system makes it possible to reach the maximum the number of users, it maximizes transmission capacity, it admits signals coming from users situated at varying distances both near and far, it avoids the production of overflows, it introduces the maximum average power for the range available to the communication and it minimizes the number of bits necessary for the analog/digital conversion in reception.

  • Method enabling multiple communication nodes to access a transmission means on an electrical grid
    Publication number: 20060120399
    Abstract: Method enabling multiple communication nodes to access a transmission means on an electrical grid, which permits access in a fair manner by nodes on a shared medium such as the electrical network, achieving the maximum access speed when there are no collisions between reservation requests and the detection of coexistence signals in a robust way in noisy environments. It is characterized by the use of signals for reservation (5) and release (10) of the communication and by the random waiting prior to a reservation of the electrical network with minimum and maximum values fixed in advance.
