    摘要: A technique is proposed to accurately estimate the Network CODEC levels for each PCM code a server modem generates. These levels are affected by the digital impairments such as Digital attenuation PAD in the trunk, the Robbed Bit Signaling, the type of CODEC (μ-law or a-law—or non standard), and by analog impairments such as loop distortion, noise, inter-modulation distortion, echo. At client modem equalizer output good estimates for these levels are derived. By detecting RBS pattern of the trunk, and using averages of decode levels of similar RBS slots, more accurate data points are obtained. By further replacing these levels with the closest CODEC receive levels, good accuracy is obtained. Non-monotonic points are detected and eliminated. An upper limit is set for constellation points to avoid saturation of the receiver. IMD correction is applied to the decode levels. Ideal points that are not signaled, are added if possible. When PAD-detection or Codec detection fails, PAD is set to 0 dB and the constellation is based on originally received and averaged data points. Techniques are presented for V.90 type modem constellation generation.

    摘要: A method of generating a data constellation at a client modem is provided whereby an optimum distance between data constellation data points may be calculated for a predetermined, acceptable error probability. An iterative process may be carried out using proposed data constellations which may be used to provide factors for calculating corrected constellations. Once a constellation is generated to satisfy the required probability of error, the constellation may be re-evaluated using CRC errors and detected noise variance at the client modem. Based upon predetermined levels of noise variance and CRC error, the constellation may be regenerated to operate at either a higher bit rate or a lower bit rate.

    摘要: An output voltage regulator of step-down switching power converters is described, with the regulator provided with digitally adjusted output voltage. It solves the problem of low regulation due to low error amplifier (EA) gain. This invention includes a power converter with the function of Digitally Error Correction, having Logic Control, EA, PWM comparator, Driver, power devices and passive components. A Digital Calibration Circuit whose input terminal is connected to the output voltage and output terminal is connected to the error signal. When the output voltage exceeds the tolerance range, this Digital Calibration Circuit will increase or decrease the error signal step by step, keeping the output voltage in the tolerance range. The Digital Calibration Circuit can be applied not only in nanometer scale process, but also in traditional process. For those power converters in traditional process, it is also quite promising in applications.

    摘要: A method for filtering a notification being provided from an application to a user of a social networking system based on an action of the user is described. The method starts by receiving the notification from the application to the user. If the notification is a first notification sent from the application to the user, the notification is displayed to the user with (i) a prompting message that includes a selectable opt in image, and (ii) a selectable opt out image. The prompting message includes a request to opt in to receiving notifications from the application. If the notification is not the first notification sent from the application to the user, the method determines whether to display the notification to the user by determining whether the user previously opted in to notifications from the application and whether click-through rate (CTR) of notifications from the application is greater than CTR threshold.
