摘要： There is provided a mechanism for controlling a transmission of data in a fragmentation transmission mode. When fragments are transmitted in a fragmentation transmission mode, it is determined whether the fragment frame is received successfully or whether an acknowledgment message for confirming a successful transmission of the fragment frame is received. In case the acknowledgment for the successful transmission of the one fragment frame is not received, or the fragment is frame is not successfully received, the fragmentation transmission mode is maintained and a retransmission of the fragment frame is initiated.

摘要： An approach is provided for subblock-wise frequency domain equalization, wherein a data block of a received signal is segmented into at least two subblocks at a receiving end of a transmission channel. The subblocks are then equalized separately in the frequency domain, and equalized subblocks are combined to obtain an equalized signal. Thereby, Doppler induced interference can be suppressed to achieve enhanced robustness to high Doppler and compensate performance degradation due to rapidly varying channels.

摘要： A QRD-M decomposition includes a first and a sequential second stage, at least. In the first stage, M branches are selected from among more than M branches entering the first stage as survive branches from which multiple decompositions are calculated. In the second stage, more than M branches are selected from among those branches entering the second stage as survive branches from which multiple decompositions are calculated. The symbol of the received signal is decided from a branch that is a survive branch of both the first and second stages. The second stage may be within a window that may include additional stages at which the pruning decision down to M survive branches is delayed. One or more windows may be used in a single QRD-M decomposition. In an embodiment, all branches entering the second stage are survive branches. It is shown that the marginal increased computational load increases accuracy.
摘要翻译： QRD-M分解至少包括第一和第二阶段。在第一阶段，从分支进入第一阶段的M个分支中选出M个分支作为计算多个分解的生存分支。在第二阶段，从进入第二阶段的那些分支中选出超过M个分支作为计算多重分解的生存分支。接收信号的符号由作为第一和第二级的存活分支的分支决定。第二阶段可能在一个窗口内，可能包括另外一个阶段，在此阶段，由M延续出来的剪枝决定被延迟。单个QRD-M分解中可以使用一个或多个窗口。在一个实施例中，进入第二阶段的所有分支都是能够分支的。显示边际增加的计算负载提高了精度。

摘要： In a multiple-input multiple output (MIMO) system, high-rate data transmission is achieved by dividing the original data stream into several parallel data substreams, each of which is transmitted from a corresponding transmit antenna (spatial multiplexing) and received by multiple receive antennas. The number of spatial streams depends on the number of antennas. In a receiver, a search-tree based QR Decomposition-M (QRD-M) algorithm is used. According to the invention, multiple spatial signal streams received from a MIMO channel are pre-ordered based on modulation alphabets of said received spatial signal streams prior to performing a QRD-M detection.

摘要： Wearable devices, methods and processor-readable media for multi-finger mid-air gesture recognition are described. A smart ring wearable device having an array of proximity sensors located about the circumference of the ring is used, in conjunction with a motion sensor such as an accelerometer, to sense and recognize multi-finger mid-air gestures. The proximity sensors may be used to sense the relative positions and shapes of the fingers of the user's hand. The motion sensor may be used to detect gross movements of the finger, hand, and arm, and to detect other movements such as finger collisions using high-frequency sampling of accelerometer data to sense bio-acoustic vibrations. A gesture-sensing system may be operated by the wearable device, a gesture-controlled device, or another device to recognize the gestures based on the sensor data using a trained support-vector machine as a classifier.

摘要： User interface control based on elbow-anchored arm gestures is disclosed. In one aspect, there is provided a method of user interface control on a computing device based on elbow-anchored arm gestures. A visual user interface (VUI) screen is displayed on a display of a computing device. The VUI screen comprises a plurality of VUI elements arranged in a plurality of VUI element levels. Each VUI element level comprising one or more VUI elements. A spatial location of an elbow of an arm of a user and a spatial location of a wrist of the arm of the user are determined. A three-dimensional (3D) arm vector extending from the spatial location of the elbow to the spatial location of the wrist is then determined. A VUI element in the VUI screen corresponding to the 3D arm vector is then determined based on a predetermined 3D spatial mapping between 3D arm vectors and VUI elements for the VUI screen.
