摘要:
Disclosed is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals that are transmitted in the same frequency bandwidth at the same time. According to the precoding method, one matrix is selected from among matrices defining a precoding process that is performed on the plurality of baseband signals by hopping between the matrices. A first baseband signal and a second baseband signal relating to a first coded block and a second coded block generated by using a predetermined error correction block coding scheme satisfy a given condition.

The present display device is a display device in which a display unit is provided with a first area (MAR) that displays a first picture and a second area (SAR) that displays a second picture, and is equipped with a first illumination unit that illuminates the first area with light and a second illumination unit that illuminates the second area with light, wherein power supply to the first illumination unit and power supply to the second illumination unit are controlled separately. Thus, it is possible to reduce power consumption.
摘要:
A transmission method simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

A display apparatus (1) having a touch panel function has a display screen (21) and multiple touch sensors (10) to detect the contact position of a user to the display screen (21), and the touch sensor (10) has a first sensor group (11a) of which the sensitivity to detect the user instruction position to the display screen (21) is relatively low, and a second sensor group (11b) of which the sensitivity to detect the user instruction position to the display screen (21) is relatively high compared to the first sensor group (11a). Thus, a display apparatus is provided having a touch panel function preventing poorer user usability, and which reduces power consumption.
摘要:
SP signals to be transmitted from a first transmitting antenna are arranged in the same pattern as SP signals to be transmitted from a second transmitting antenna. The SP signals to be transmitted from the second transmitting antenna in one symbol are generated, such that the polarity of the SP signals are alternately inverted and non-inverted with respect to the SP signals to be transmitted from the first transmitting antenna in the same symbol. Thus, in the direction that the symbol number is incremented by 1 and the carrier number is incremented by 3, the polarity of SP signals transmitted from the second transmitting antenna are all inverted or non-inverted with respect to the polarity of corresponding SP signals transmitted from the first transmitting antenna.

摘要:
Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

A challenge to be met by the present invention is to provide an electronic component mounting machine and an electronic component loading head in which the loading head has two rows of nozzle shafts and that can promote miniaturization of the machine by minimizing the loading head. In a loading head having two rows of nozzles (L1 and L2) including a plurality of nozzle shafts arranged in rows and at a predetermined nozzle arrangement pitch, a θ rotary drive mechanism that rotates the nozzle shafts around their axes is configured so as to include driven pulleys (28) coupled to the respective nozzle shafts; a plurality of idlers (30) interposed between the two rows of nozzles (L1 and L2); and endless drive belts (29A and 29B) that transmit rotation of the θ-axis motors (27A and 27B) to the driven pulleys (28). Drive surfaces (29a) of the respective driving belts (29A and 29B) are looped around the respective drive pulleys and the respective driven pulleys, and the other sides of the respective drive surfaces (29a) are looped while guided by the idlers (30).
