Abstract: Methods, apparatuses and systems for identifying a channel bandwidth and channel offset of an orthogonal frequency division multiplexing (OFDM) signal. The OFDM signal is received by a receiver apparatus that may be tuned to RF bandwidth of 20 MHz, 40 MHz or 80 MHz. The method utilized by the apparatus includes identifying the location of the primary channel and subsequently determining a sequence of equalized frequency domain sub-symbols of the signal field in the lower and the upper frequency band. Further, a cross-correlation between the sequence of equalized frequency domain sub-symbols is computed along with the computing energy of the sequence of equalized frequency domain sub-symbols. Finally, the cross-correlation and the computed energy are compared for identifying the channel offset and the channel bandwidth.

Abstract: A method and system target an audience segment in real-time based on social activities of users. A set of keywords associated with a brand and a set of keywords associated with a first plurality of users is compared. When there is match between the two sets of keywords, a seed audience segment that includes a subset of the first plurality of users is generated. User profiles of users from the seed audience segment based on features are generated. Subsequently, model files of features, feature threshold scores, and an overall feature threshold score corresponding to the user profiles are calculated and provided to a real-time bidding (RTB) server. When the RTB server receives a bid request for a cookie, the RTB server computes a model score corresponding to the cookie based on the model files and accepts the bid request if the model score is above the overall feature threshold score.
