Then, it may be determined, based on the identity of the user, that the detected gesture corresponds to at least one command of a plurality of commands. Subsequently, the at least one command may be executed. In some arrangements, the gesture may correspond to a first command when performed by a first user, and the same gesture may correspond to a second command different from the first command when performed by a second user different from the first user. | 06-20-2013 |

20090245154 | SIGNALING PARAMETERS CHANNEL PROCESSING - In a multicasts wireless telecommunication system providing an aggregation of one or more independent data components as a flow, wherein the OIS is located at the latch point of the beginning of the superframe, and the OIS programming is latched at the superframe boundary, the improvement of deriving signal parameter information from Signaling Parameter Channel (SPC) symbols transmitted in a Forward Link only (FLO) network by deriving a time domain channel estimate by assuming each of the combinations for the signal parameter field in the scrambler seed and picking the signal parameter combination that yields the most energy in the time domain above a threshold value. | 10-01-2009 |
20100002785 | ADAPTIVE THRESHOLDING FOR OFDM CHANNEL ESTIMATION - An adaptive thresholding technique eliminates suboptimum threshold values by adjusting for varying channel conditions to eliminate interference where no channel energy is present, without discarding viable taps having useful channel energy. The adaptive thresholding technique adaptively optimizes receive threshold values for both wide and local area channels based only on measured C/I ratios 300. Thresholds are calculated based on instantaneous C/I estimates and/or weighted average C/I estimates calculated from WID/LID energies obtained from the current superframe WIC/LIC symbols respectively. In alternate embodiments, thresholds are calculated based on instantaneous C/I estimates and/or weighted average C/I estimates calculated from WTPC and LTPC symbols for the wide and local area channels, respectively The present adaptive thresholding technique dynamically reduces the threshold as the C/I estimate increases to mitigate performance degradation due to removal of weak signal taps. There is a separate threshold for each of the 12 coding and modulation modes supported by an exemplary receiver. | 01-07-2010 |
20100046675 | METHODS AND APPARATUS FOR TRANSMITTING LAYERED AND NON-LAYERED DATA VIA LAYERED MODULATION - A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation. | 02-25-2010 |
