    Abstract: A transmission apparatus includes M signal processors that respectively generate modulated signals directed to M reception apparatuses, M being an integer equal to or greater than 2, and an antenna section. Each signal processor modulates a first bit sequence made up of two bits to generate a first modulated signal and a second modulated signal, and modulates a second bit sequence made up of other two bits to generate a third modulated signal and a fourth modulated signal, in a case of transmitting multiple streams to a corresponding one of the M reception apparatuses. The antenna section includes a first antenna that transmits the first modulated signal and the third modulated signal and a second antenna that transmits the second modulated signal and the fourth modulated signal. At least either the signals transmitted from the first antenna or the signals transmitted from the second antenna are phase-changed signals.

    Abstract: A transmission device includes a first mapper, a second mapper, a converter, a superposer, and a transmitter. The first mapper is configured to map a first bit stream of a first data series to generate a first modulated symbol stream. The second mapper is configured to map a second bit stream of a second data series to generate a second modulated symbol stream. The first modulated symbol stream and the second modulated symbol stream are representable on a complex plane extending in a first direction and a second direction. The converter is configured to convert the second modulated symbol stream in accordance with the first modulated symbol stream only in the first direction on the complex plane. The superposer is configured to superpose the first modulated symbol stream and the second modulated symbol stream converted by the converter, at an amplitude ratio, to generate a multiplexed signal.

    Abstract: A dictation device includes: an audio input device configured to receive a voice utterance including a plurality of words; a video input device configured to receive video of lip motion during the voice utterance; a memory portion; a controller configured according to instructions in the memory portion to generate first data packets including an audio stream representative of the voice utterance and a video stream representative of the lip motion; and a transceiver for sending the first data packets to a server end device and receiving second data packets including combined dictation based upon the audio stream and the video stream from the server end device. In the combined dictation, first dictation generated based upon the audio stream has been corrected by second dictation generated based upon the video stream.

    Abstract: The present disclosure relates to transmission and reception of data in a wireless communication system, the wireless communication system supporting aggregation of a plurality of component carriers and an additional carrier accessible by a listen before talk approach. In particular, monitoring is performed of a search space on a cross-scheduling component carrier for detecting downlink control information having a carrier identification field indicating the cross-scheduling component carrier as well as for detecting downlink control information with the carrier identification field indicating the additional carrier, wherein the search space is specified by a subset of resources, associated with carrier identification of the cross-scheduling component carrier but is not associated with carrier identification of the additional carrier. Then data are transmitted or received on the carriers in accordance with the received downlink control information.

    Abstract: The present disclosure relates to the design of a fast binaural rendering for multiple moving audio sources. This disclosure takes the audio source signals which can be object-based, channel-based or a mixture of both, associated metadata, user head tracking data and binaural room impulse response (BRIR) database to generate the headphone playback signals. The present disclosure applies a frame-by-frame binaural rendering module which takes parameterized components of BRIRs for rendering moving sources. In addition, the present disclosure applies hierarchical source clustering and downmixing in the rendering process to reduce computational complexity.
