    Abstract: A method and an apparatus of compensating for a signal receiving error at a receiver in a packet-based communication system. In the invention, frequency offset estimation and DC offset estimation obtained in a current packet are re-used in a next packet if the receiver is an intended recipient of the current packet and the current packet is received correctly, verified by CRC-32 checking in the PHY layer and the DA checking in the MAC layer, respectively. Thereby, the overall receiver performance and stability can be improved from packet to packet and the estimation algorithm is simplified.

    Abstract: A method for implementing an equalizer of an orthogonal frequency division multiplexing (OFDM) baseband receiver is provided. The OFDM baseband receiver includes a channel estimation and tracking module for estimating a channel impulse response of an input signal of the equalizer. A conjugate of the channel impulse response is first calculated. The input signal and the conjugate of the channel impulse response are then multiplied to generate a product signal. The product signal is then taken as the output signal of the equalizer without dividing the product signal by a channel state information, wherein the channel state information represents a square of an absolute value of the channel impulse response.

    Abstract: A SIP Gateway (SIPGW) coupled to an IP Multimedia Subsystem (IMS) is disclosed that detects when a first party, using a Plain Ordinary Telephone Service (POTS) telephone coupled to the SIPGW and participating in a call, performs a hook flash action. In response, the SIPGW sends to the IMS a first SIP INFO message indicating that the POTS telephone has performed the hook flash. In response to a first SIP INFO message indicating that a first party has performed a first hook flash, an Application Server (AS) in an IMS places on hold a second party participating in the call. The AS may also cause a Media Server to receive information from the first party identifying a call feature to be provided, where the call feature is one of simple call hold, consultation call hold, attended call transfer and unattended call transfer.

    Abstract: A method for updating coefficients in a decision feedback equalizer (DFE). The DFE comprises an ISI canceller for canceling ISI from a plurality of first signals received from a channel. A first symbol comprising a set of the first signals is decoded to generate a decoded symbol. Then, a vector of error values computed as the difference between the decoded symbol, and the first symbol is obtained. According to the decoded symbol and the vector of the error values, a temp matrix is generated. Next, the values of the elements in every diagonal line of the temp matrix are averaged. Finally, the coefficients are updated by the Toeplitz Matrix.

    Abstract: A process is proposed that enables a widget vendor or aggregator to continuously present widgets via a widget network to a user who previously grabbed and embedded a first widget presented by the vendor or aggregator. The user may initiate the browsing of the widget network from a user placement where the first widget is embedded to choose and grab a second widget from the vendor. Here, the widgets in the widget network can be dynamically maintained and updated by the vendor and can be created at a time after the first widget was grabbed by the user. If the user grabs the first widget over the web and embeds the widget into his/her own placement, the user is presumably interested in the widget and it is likely that the user may also be interested in other widgets created by the same vendor or in the same category of interest.

    Abstract: The present invention discloses a method and apparatus of IQ imbalance compensation for a receiver. The repetitive attribute of the preamble in a signal received by the receiver is used to estimate the IQ imbalance parameters. The data carried by the preamble repeats itself every N sampling intervals. A MSE equation is derived based on assuming the ratios between any two sampling points separated by N samples are identical, and the IQ imbalance parameters can be estimated by solving the MSE equation using the LS algorithm. Consequently, the IQ mismatch offset of the signal is compensated according to the estimated parameters.
