  • Method for reducing the energy consumption in a wireless communication terminal and communication terminal implementing said method
    Patent number: 9380527
    Abstract: The invention relates to a wireless communication terminal able to transmit and/or receive video, audio or data signals in a first and a second frequency band comprising a first MIMO circuit of N paths (N?1) operating in the first frequency band and a second MIMO circuit of M paths (M?1) operating in the second frequency band, the first and second MIMO circuits each being coupled to front-end modules comprising respectively N and M power amplifiers, the front-end modules being connected to an antenna system.

  • Wideband transceiver device for transmitting and receiving signals from a channel selected in dynamically spread bandwidth
    Patent number: 9124340
    Abstract: The proposed process makes it possible to noticeably and dynamically increase the operational frequency band of a wideband emission/reception device without performance degradation, this thanks to the implementation of a particular architecture and a judicious distribution of the technical constraints over the analogue and digital sub-assemblies of a user terminal.

  • Gain control method and device for a bursty data frame reception system
    Patent number: 7953191
    Abstract: The gain control method for the RF and IF amplification stages of a bursty data frame reception system enables, following a step for evaluating the received signal strength, the gain adjustment step of the RF amplification stage to be temporarily deferred until a frame structure symbol is received, during which the gain adjustment step of the IF amplification stage takes place simultaneously with that of the RF gain, while retaining an overall gain linearly dependent on the input signal strength.
