摘要： An information recording medium is provided with a wobbled track, wherein at least a part of the track is subjected to wobbling based on a wobble signal in which at least a part of recording information is randomized. Each track is wobbled at a randomized frequency, so that a frequency of a wobbling signal obtained from the wobbled track is randomized. As a result, the influence of crosstalk between adjacent track is reduced.

摘要： An error detector at a receiver comprises a feedback shift register. A shift direction in the feedback shift register is opposite to a shift direction at a transmitter in generating a transmission bit string by using a specified generator polynomial. A reception bit string is inputted to the feedback shift register in reverse order to the transmission bit string generated at the transmitter so that errors in the reception bit string are detected by obtaining the remainder. Another error detector at a receiver comprises first and second feedback shift registers. Respective shift directions in the first and second feedback shift registers are the same as and opposite to a shift direction at a transmitter in generating a transmission bit string. The reception bit string is inputted to the first feedback shift register in the same order in which the transmission bit string was generated, while the reception bit string is inputted to the second feedback shift register in reverse order to one which the transmission bit string was generated. Errors in the reception bit string are detected by comparing respective remainders obtained by the first and second feedback shift registers. This reduces the processing time required for the error detection and increases efficiency in detecting errors in transmitted data.

摘要： A state machine that can be tested easily is disclosed. A state machine has a latch for storing data representing an intended state and a state control unit for producing data representing a subsequent state according to an intended state provided by the latch and a detection signal, and makes state transitions consecutively. The state machine comprises a state data input unit for inputting data representing an intended state directly from an external unit, a selector for selecting either data provided by the state control unit or data provided by the state data input unit so as to supply selected data as data representing a subsequent state to the latch, and a control data input unit for externally inputting control data for use in controlling the selection performed by the selector. After data representing an intended state is fed to the state data input unit, when control data requesting the selector to select data provided by the state data input unit and to send the data to the latch is input via the control data input unit, the latch latches data representing an intended state synchronously with a clock and thus retains the intended state.

摘要： A receiving unit, receiving method, and semiconductor device that reduce the size of circuits in a receiving unit. A receiving section receives signals sent from a base station and transmitted through a plurality of paths. A path tracking section detects timing of each of the plurality of paths through which the signals received by the receiving section were transmitted. A demodulating section demodulates the received signals by performing a despreading process according to the timing of the plurality of paths detected by the path tracking section. A correlation value calculating section calculates a correlation value between the received signals and a spreading code. A destination selecting section provides output from the correlation value calculating section to the path tracking section in the case of performing a path tracking process by the path tracking section and provides output from the correlation value calculating section to the demodulating section in the case of demodulating the received signals by the demodulating section.

摘要： An optical transceiver unit capable of preventing any crosstalk from an optical transmitter to an optical receiver to thereby avert reduction of the reception sensitivity. The optical transceiver unit comprises a multilayer printed circuit board, a lower case for housing the multilayer printed circuit board therein, and an upper case so disposed as to cover the lower case for enclosing the multilayer printed circuit board in an assembly of the two cases. A light emitting element module and a light receiving element module are attached to one side wall of the lower case. The printed circuit board has a first region where a transmitting circuit is formed, and a second region where a receiving circuit is formed. The first and second regions are completely isolated electromagnetically from each other by a first shield plate fixed to the lower case and a second shield plate fixed to the upper case.
