摘要： The invention provides a receiver associated with a body, e.g., located inside or within close proximity to a body, configured to receive and decode a signal from an in vivo transmitter which located inside the body. Signal receivers of the invention provide for accurate signal decoding of a low-level signal, even in the presence of significant noise, using a small-scale chip, e.g., where the chip consumes very low power. Also provided are systems that include the receivers, as well as methods of using the same.

摘要： Une syntonisation précise d'un démodulateur par rafales d'un système de satellite sur un signal qui est soumis à un décalage de fréquences au cours de sa transmission par la liaison satellite est effectuée sans l'utilisation d'oscillateurs de haute précision en des points éloignés ni de la transmission d'une tonalité pilote spécialisée. Par contre, un signal d'horloge spécialisé de haute précision est utilisé pour la porteuse du canal retour. La modulation des données sur la porteuse de liaison de sortie est également dérivée de la source d'horloge de précision. A chaque station éloignée (30), le canal de liaison de sortie est contrôlé pour récupérer le signal d'horloge de haute précision. Ce signal d'horloge récupéré est ensuite utilisé comme référence pour générer la porteuse de canal retour. Le démodulateur par rafale au niveau de la station mère (10) contrôle à la fois la porteuse continue du canal de liaison de sortie et les transmissions en mode rafale provenant des stations à distance. Chacune des porteuses en mode continu et par rafale ayant été transmise par l'intermédiaire du satellite (20) subit le même décalage ou la même modification de fréquence, de sorte que la différence de fréquence entre la porteuse de canal de liaison de sortie et la porteuse de canal de liaison retour est toujours constante. La porteuse de canal de liaison de sortie, qui est disponible sur une base continue, est utilisée pour dériver une référence de fréquence d'oscillateur local en vue d'établir la référence de l'oscillateur local du démodulateur par rafales.

摘要： Certain aspects of the present disclosure provide methods and apparatus for autonomous receive (RX) detection. One example method for wireless communications generally includes powering down a portion of a receive path in a first module; detecting, in a second module comprising another portion of the receive path, that a radio frequency (RF) signal has been received by the second module while the portion of the receive path in the first module is powered down; and sending a control signal to power up the portion of the receive path in the first module, based on the detection.

摘要： A least squares estimator of carrier phase and amplitude in a receiver in a communication system using a phase shift keying modulation scheme that uses both known pilot symbols and unknown data symbols is described. That is, the method exploits knowledge of pilot symbols in addition to the unknown data symbols to estimate carrier phase and amplitude. Further, an efficient recursion based estimation method is described that only requires O(L. log L) arithmetic operations where L is the number of received signals. This method uses the M-Ary rounded phase offsets to sort the data symbols and this sorted order is used to recursively calculate candidate values in an optimization process. Simulation results show that the estimation methods Using data and pilot symbols outperform estimation methods using only data symbols (ie non-coherent detection methods). Further, the system can be used for systems using multiple M-ary phase shift keying digital modulation schemes.

摘要： A method of rapid non-data aided carrier signal acquisition for a low symbol rate carrier signal, comprising receiving and converting an analog intermediate frequency carrier to a digital carrier signal, down-converting the signal to substantially baseband, reducing a sampling rate of the digital carrier signal using a decimation filter, determining a highest Fast Fourier Transform (FFT) based on a result of one or more FFT's generated by an FFT module using a peak finder, selecting an input source for the FFT module using a multiplexer, generating a frequency estimate of the digital carrier signal using a walking coarse detector, tuning a carrier recovery loop (CRL) based on the frequency estimate generated by the walking coarse detector, determining a final carrier frequency offset estimate using a result of the FFT module, modulation removal, and the peak finder, and programming an oscillator within the CRL to the final carrier frequency offset estimate.

摘要： A data receiving system has a radio frequency unit for demodulating a series of signals transmitted at a carrier wave frequency, a local oscillating unit for generating a demodulating frequency used for the demodulation of the series of signals, an equalizing unit for removing a distortion of the series of signals demodulated in the radio frequency unit, a phase shift estimating unit for taking out phase information from the series of signals, calculating a time changing rate of the phase information and estimating a phase shift caused by a difference between the carrier wave frequency and the demodulating frequency according to the time changing rate, and a correcting unit for correcting the series of signals transmitted from the equalizing unit according to the phase shift to remove the phase shift from the series of signals. Accordingly, because the phase shift is estimated by using the phase information placed in the series of signals, an influence of a bit pattern of a series of training bits arranged in the series of signals can be removed.
