  • Publication number: 20200366532
    Abstract: Apparatus and methods for sounding reference signal (SRS) switching are provided. In certain embodiments, transmit path resources of UE are used to reduce or eliminate the impairment of SRS upon transport capacity. Furthermore, the transmit path resources can be used for other purposes, and thus SRS switching time can be reduced by re-using transmit path resources that may be included for other purposes. The teachings herein can be used to achieve SRS switching of 0 ?s, thereby eliminating the impact of switching timing constraints for SRS symbols on transport capacity.

  • Publication number: 20190318055
    Abstract: The invention relates to a method for determining the dimensions of an electrochemical cell allowing a total area of the electrochemical cell to be minimized while maximizing an electrical signal generated by the electrochemical cell in operation, including: a/ determining a first cost function expressing the variation in a first parameter representative of the total area as a function of an adjustment variable representative of an aspect ratio of the active zone; b/ determining a second cost function expressing the variation in a second parameter representative of the generated electrical signal as a function of the adjustment variable; c/ determining a compound cost function from the first and second cost functions and identifying a value of the adjustment variable that optimizes the compound cost function and that therefore conjointly optimizes the first and second cost functions.

  • Publication number: 20190286407
    Abstract: Audio and video systems for checking safety sounds and telltales are provided. The audio system includes a digital signal processor with a plurality of safety sounds and a plurality of signatures corresponding thereto. A head unit controller includes a signature and volume checker to identify an expected signature of the one of the safety sounds. The digital signal processor outputs a mixed audio stream and includes a lower bit inserter to replace lower bits of the mixed audio stream with replacement lower bits based on the signature and output a modified audio stream. A lower bit extractor separates and outputs the replacement lower bits and a remainder of the modified audio stream. An audio amplifier unit receives and outputs the remainder of the modified audio stream. The head unit controller rebuilds the signature, determines whether the signature matches the expected signature, and sends an acknowledgment accordingly.

  • Patent number: 9461853
    Abstract: An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analogue portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analogue AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analogue gain can be common to all branches, based on measurement of the analogue signal in each branch.

  • Patent number: 9059795
    Abstract: A method for dynamically clocking one component located into a Wireless telecommunication apparatus comprising a RF transceiver subject to desensizitation by said component EMI, characterized in that it involves the steps of performing an adaptive control on the clock rate of said component so as to locate a wideband noise PSD null just to the left or to the right, in the frequency domain, of the RF transceiver wanted carrier frequency (fw) Particularly, the control is performed by means of the control of programmable frequency dividers, and under the control of a general control unit (UCM) for the purpose of performing a contextual analysis of the current mode of operation of said wireless telecommunications and, in response to said contextual analysis, for determining the fine tuning of the clock rate to be applied to said component.

  • Patent number: 8437725
    Abstract: Process for controlling the switching of the data rate at a digital interface exchanging data and control messages between a Radio Frequency (RF) circuit and a digital circuit, comprising the steps of: setting by default the data rate to a low speed (LS) rate having a density presenting a first lobe being inferior to the frequency band considered in said RF circuit so as to prevent desensitization of the LNAs by the noise produced by said digital interface; storing the data and control messages message into a FIFO and monitoring the level of said FIFO; whenever the level of said FIFO reaches a predetermined threshold value, then controlling said interface to switch to a second high speed (HS) rate in order to flush said FIFO. In one embodiment, the LS frequency is set to a value of 832 MHz, thus preventing simultaneously desensitization of the GSM band and also the GPS band.
