    摘要： A mobile platform efficiently processes sensor data, including image data, using distributed processing in which latency sensitive operations are performed on the mobile platform, while latency insensitive, but computationally intensive operations are performed on a remote server. The mobile platform acquires sensor data, such as image data, and determines whether there is a trigger event to transmit the sensor data to the server. The trigger event may be a change in the sensor data relative to previously acquired sensor data, e.g., a scene change in an image. When a change is present, the sensor data may be transmitted to the server for processing. The server processes the sensor data and returns information related to the sensor data, such as identification of an object in an image or a reference image or model. The mobile platform may then perform reference based tracking using the identified object or reference image or model.

    摘要： Methods and circuits for positioning a signal sampling window within a wireless receiver device for use in a multi-transmitter wireless broadcast network include generating a long channel model based upon a signal identifying transmitters that can be processed without aliases, and positioning the signal sampling window based upon the long channel model. For example, in a MediaFLO® broadcast, the long channel model may be generated by receiving positioning pilot channel (PPC) signals. Positions for the signal sampling window may be determined by identifying hypothetical signal sampling window positions, calculating signal to interference and noise ratio (SINR) values for each identified hypothetical, and selecting the hypothetical with the best SINR. Using a long channel model to position the signal sampling window may provide improved window placement, reduce destructive aliasing, and reduce a time guard in the window placement. The long channel model may be used in conjunction with terrain databases.

    摘要： Methods and devices for encoding and interleaving data packets for broadcast and for de-interleaving and decoding data packets in a communication system eliminate detrimental biasing effects by using pseudo-random M-sequence bit encoding as part of the turbo encoding and decoding. The use of pseudo-random M-sequence bit encoding mitigates biasing effects that may otherwise be introduced if conventional r-c interleaving is applied to long turbo encoded data which would degrade reception in the presence of broadcast interference.
