Abstract: A precoding process is performed on a first baseband signal and a second baseband signal to generate a first precoding signal and a second precoding signal. A pilot signal is inserted into the first precoding signal and phase change is performed on the second precoding signal. A pilot signal is inserted into the phase changed second precoding signal, and phase change is further performed on the phase-changed second precoding signal with the pilot signal inserted.

Abstract: An anomaly detection method includes: extracting, for each of a plurality of learning packets obtained, all possible combinations of N-grams in the payload included in the learning packet; counting a first number which is the number of occurrences of each combination in the payloads of the learning packets; calculating, as anomaly detection models, first probabilities by performing smoothing processing based on a plurality of the first numbers; and when the score calculated for each of a plurality of packets exceeds a predetermined threshold that is based on the anomaly detection models stored in a memory, outputting information indicating that the packet having the score has an anomaly.

Abstract: A transmission device includes: a first mapper that maps a first bit stream of a first data series to generate a first modulated symbol stream of the first data series; a second mapper that maps a second bit stream of a second data series to generate a second modulated symbol stream of the second data series; a converter that subjects the second modulated symbol stream to conversion in accordance with the first modulated symbol stream; a superposition unit that superposes the first modulated symbol stream and the second modulated symbol stream at a predetermined amplitude ratio to generate a multiplexed signal, the second modulated symbol stream having been subjected to the conversion in accordance with the first modulated symbol stream; and a transmitter that transmits the multiplexed signal.

Abstract: A sound source estimation unit (101) estimates, in a space as a target of sparse sound field decomposition, an area where a sound source is present at second granularity that is coarser than first granularity of a position where a sound source is assumed to be present in the sparse sound field decomposition. A sparse sound field decomposition unit (102) decomposes an acoustic signal observed by a microphone array into a sound source signal and an ambient noise signal by performing a sparse sound field decomposition process at the first granularity for the acoustic signal in the area at the second granularity where the sound source is estimated to be present in the space.

Abstract: A control apparatus, that can expand a range in which noise generated in an unmanned flying object is reduced, is provided. The control apparatus acquires position information of one or more unmanned flying objects and noise information concerning first noises generated by the one or more unmanned flying objects. The control apparatus also acquires output region information indicating an output region of sound output from a speaker. The control apparatus calculates, using the position information, the output region information, and the noise information, second noises that reach the output region. The second noises are caused by the first noises which are generated by the one or more unmanned flying objects. The control apparatus generates opposite phase signals for outputting opposite phase sounds with respect to the calculated second noises, and causes the speaker to output sound on a basis of the generated opposite phase signals.

Abstract: An integration server manages production in a manufacturing line that includes a first stage and a second stage carried out after the first stage. The integration server includes a communicator that acquires a first production log and a second production log. The first production log includes a first production count of processing objects in the first stage. The second production log includes the number of processing objects in the second stage. The integration server also includes an irregularity detector that detects the presence of irregularity in the first production log and the second production log on the basis of the first production count and the number of the processing objects in the second stage.

Abstract: A control method of a personal authentication apparatus and a personal authentication apparatus stores a piece of authentication information of a predetermined user. The method and apparatus estimates an emotion felt by a target user, based on a physical quantity acquired by a sensor, generates identification information that identifies an object that causes the target user to feel the estimated emotion, based on the physical quantity acquired by the sensor or presentation information presented by a presenter, and determines whether the target user is the predetermined user based on the estimated emotion and the generated identification information and the piece of authentication information of the predetermined user.

Abstract: A reception processor receives the cell detection reference signals, each of the cell detection reference signals being transmitted from corresponding one of a plurality of cells. An RRM report generator generates measurement information indicating a measurement result of reception quality measured using the cell detection reference signal. A transmission processor transmits the measurement information. The cell detection reference signals are mapped to any one of a plurality of candidate resources, which is a part of a plurality of resources set for other reference signals in a subframe to which the cell detection reference signals are mapped.

Abstract: Provided are a base station, user equipment and wireless communication methods related to DCI design for blind detection. A base station comprises: circuitry operative to align, for each DCI of a first group of DCIs, one of the size of the DCI of the first group and the size of a selected DCI of a second group of DCIs with the other, if the size of the DCI of the first group is different from the size of each DCI of the second group of DCIs, wherein the selected DCI of the second group is a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes larger than the size of the DCI of the first group or a DCI whose size is closest to the size of the DCI of the first group among DCIs of the second group having sizes smaller than the size of the DCI of the first group; and a transmitter operative to transmit the first group of DCIs and the second group of DCIs after the size alignment by the circuitry to a user equipment, wherein the size alignment is based on a rule which is known by the base station and the user equipment beforehand.

Abstract: A playback device reads out from a recording medium and plays multiple High Dynamic Range (HDR) video streams that are encoded with video information. The playback device includes a first register, a second register and a playback unit. For each of the HDR video streams, the first register stores first information indicating whether the playback device corresponds to or not, and the second register stores second information indicating whether a display device connected to the playback device corresponds to or not. The playback unit plays the HDR video streams using a playback format selected based on a playback program stored in the recording medium, in a case where the first information and the second information indicate that there are multiple playback formats corresponding to both the playback device and the display device.
