Abstract:
Systems and methodologies are described that facilitate utilizing dedicated reference signal in connection with downlink transmissions. A dedicated reference signal can comprise a set of dedicated reference symbols, which are inserted into a resource block in accordance with a specification provided by a dedicated reference signal structure. The dedicated reference signal structure can vary according to a rank utilized in the downlink transmission.
Abstract:
A device is provided. The device comprises of a waveform decompression decoder, Signal-to-noise ratio (SNR) Weighted Combining unit for multiple antennas, Frequency Domain Maximum Ratio Combining (MRC) Equalizer, Time Domain Maximum Ratio Combining (MRC) Equalizer, Equal Gain Combining Unit, and Selective Combining Slicer. The method for producing the device is also provided.
Abstract:
This invention is a method to quickly characterize the time variant channel state information to enable ATSC HDTV signal reception in a mobile environment (e.g. in a moving car, walking, on a bus, etc.) by removing the Doppler interference. The invention relates to a single or multiple antenna ATSC terrestrial DTV receiver for indoor and mobile users.
Abstract:
An apparatus includes an interleaver configured to interleave encoded data and to output a series of interleaved bits to be transmitted via a 1 MHz orthogonal frequency-division multiplexing (OFDM) transmission. The apparatus also includes a modulator configured to modulate the interleaved bits and a transform module configured to transform the modulated bits. A transmit module of the apparatus is configured to transmit the transformed bits included in one or more spatial streams of the 1 MHz OFDM transmission.
Abstract:
The subject disclosure is directed towards securing electronic commercial activity. Geo-locations are determined for one Internet transaction and another Internet transaction. These Internet transactions are related based on a common credential. Using timestamps, a relative travel speed between the geo-locations is computed for the Internet transaction and the other Internet transaction. Based upon the relative travel speed, a security component may invalidate the Internet transaction and/or the other Internet transaction.
Abstract:
Certain aspects of the present disclosure relate to techniques for constructing a long training field (LTF) sequence in a preamble to reduce a peak-to-average power ratio (PAPR) at a transmitter.
Abstract:
The embodiments described herein relate to web service client/server systems. According to some embodiments, there is provided a web service system including at least one client processor adapted to generate and transmit at least one piped request comprising a plurality of discrete requests and at least one server processor in data communication with the client processor. The at least one server processor is adapted to receive the at least one piped request comprising the discrete requests, de-pipe each discrete request from the piped request and execute each discrete request to generate a result associated with the discrete request.
Abstract:
Systems and methods for providing coverage to a first cell through a first antenna system and coverage to a second cell through a second antenna system. Data is also processed for transmission to a mobile device in the first cell using the first and second antenna systems.
Abstract:
Systems, methods, and computer program products for remote configuration of one or more power supplies, particularly lighting power supplies, are disclosed. A configuration signal that includes a setting for a parameter is generated and then transmitted to a power supply. The power supply decodes the configuration signal and, if one or more certain conditions are met, configures the power supply according to information provided in the configuration signal.
Abstract:
A securing device includes a securing member defining a securing hole therein, and a fastener extending through the securing hole. The fastener includes a spring, and a bolt having a main portion, a bottom fixing portion, and a top head portion. The securing hole includes a large portion, a small portion, and a concave around the small portion. A diameter of the small portion is greater than the main portion and smaller than the fixing portion. A diameter of the large portion is greater than the fixing portion and smaller than the spring. The main portion extends through the small portion with the fixing portion tightly abutting the securing member. The spring is mounted around the main portion and received in the concave. The spring is compressed between the head portion and a step of the securing member in the concave.
