Abstract: A method for increasing a level of distribution of a media file includes receiving an identification of metadata of a media file, the metadata including at least one keyword. The method includes directing a semantic engine to map the at least one keyword to a plurality of candidate target segments, each of the plurality of candidate target segments associated with one of a plurality of social network platforms. The method includes providing access to an enumeration of the mapped plurality of candidate target segments. The method includes receiving an identification of a subset of the plurality of candidate target segments. The method includes directing the semantic engine to strengthen an association between each of the identified subset and the at least one keyword. The method includes generating a recommendation for a method to increase a distribution level of the media file based upon at least one of the identified subset.

Abstract: An apparatus is provided for transmitting a signal in a communication system. Upon receipt of an information vector, the apparatus includes converting the information vector into a plurality of sub-information vectors; performing coding and modulation on each of the sub-information vectors according to a corresponding mode thereby generating a modulation symbol; interleaving the modulation symbol generated for each of the sub-information vectors; allocating power to the interleaved modulation symbol for each individual mode; and beamforming the modulation symbols power-allocated for each individual mode, and transmitting the beamforming symbols.

Abstract: Optimum usage of time diversity and significantly higher data rates are achieved by utilizing an adaptive Ultra-wideband impulse radio (UWB IR) transmission scheme based upon information about the channel state at a particular time instant. Through the use of channel state information, the transmission scheme is adjusted for the particular channel state. In particular, the system is adapted dynamically for each user by varying the number of pulses transmitted per bit in response to the channel state. The channel state is a dynamic parameter of the transmission system that is typically measured or estimated by the receiver. An adaptation element responds to the channel state information to determine a desired number of pulses per bit to be utilized in a transmission channel for subsequent UWB IR communication. This desired number of pulses per bit is then supplied to and used by an adaptive transmitter for subsequent transmission by a particular mobile station.
