摘要:
A multicarrier transmitter apparatus capable of improving information transmission efficiency regardless of the attenuation characteristic of a bandpass filter used. In this apparatus, BPFs (124,126) limit the bands of transmitted data. A padding position calculating part (102) decides, based on the attenuation characteristics of the BPFs (124,126), an insertion position at which to insert padding bits in the transmitted data. A padding part (103) inserts the padding bits at the insertion position decided by the padding position calculating part (102).

An electromagnetic control valve has a passage for conducting fluid. An electromagnetic actuator generates an electromagnetic force. A main valve body opens and closes the passage in accordance with the electromagnetic force generated by the electromagnetic actuator. A bypass is formed in the main valve body. A sub valve body opens and closes the bypass in accordance with the electromagnetic force generated by the electromagnetic actuator. The electromagnetic force generated by the electromagnetic actuator is adjusted such that the sub valve body is opened and closed while the main valve body closes the passage.

At a base station apparatus, known pilot signals for use in channel estimation are transmitted, and in addition thereto MCS pilot signals that are used to perform adaptive modulations respectively corresponding to a plurality of modulation schemes are multiplexed and output. A mobile station apparatus dispreads the respective MCS signals out of the multiplex signal, compares these to known symbols patterns, and sends the MCS pilot signals that show a matching relationship to the base station apparatus as a mobile station reception result. Upon receiving the mobile station reception result from the mobile station apparatus, the base station apparatus selects the modulation scheme of the optimum modulation level for the downlink signals. This configuration makes it possible to switch the modulation schemes in an accurate and simple way.
摘要:
An error correction coding apparatus which improves the throughput of the whole system, while minimizing the increase of the circuit size and the amount of processing operation of the whole apparatus. In this apparatus, a data divider 132 divides transmission data into a plurality of blocks to generate n divided blocks. The n error correction coders out of N error correction coders 134 carry out an error correction coding on each of the n divided blocks in units of block, and outputs the divided blocks. A data concatenator 136 concatenates the n code blocks that have been error-correction-coded in units of block. A division/concatenation controller 138 controls at least one of data divider 132 and data concatenator 136 so that the division of the transmission data and the concatenation of the code blocks are carried out in units of bit.

Disclosed are an interleaving device and an interleaving method which shorten processing time for channel interleaving. A CQI memory writing unit (101) writes the CQI in symbol units in the row direction from the head of the memory (103) selected as a channel interleaving line. The DATA memory writing unit (102) continues from the CQI writing end address number and symbol number and writes the DATA in symbol units in the row direction of the memory (103) selected as the channel interleaving line. The memory reading unit (104) reads the stored CQI and DATA from the memory (103) according to the channel interleaving line mapping, from the head of the memory (103) in the row direction in symbol units. The data multiplexing unit (105) multiplexes RI channel interleaving data and ACK channel interleaving data with the read CQI and DATA and outputs it as channel interleaving data.
摘要:
An information processing apparatus comprises a display which is capable of displaying a display area thereon, and the display area is associated with a running program and is either active or inactive. The information processing apparatus also comprises a first user interface to detect an event representing a request to adjust a sizing of content displayed within the display area, a second user interface to receive data indicating a position of a pointer when the first user interface detects the event, and a control unit configured to adjust the sizing of the content in response to detection of the event by the first user interface in the case that the pointer's position that the second user interface receives is in the display area, regardless of whether the display area is active or inactive.
