摘要： An optical disc drive according to the present invention can read and/or write data from/on an optical disc with information layers including first and second information layers (L0 and L1). The drive includes: an objective lens for converging a light beam; a lens actuator for driving the lens; a photodetector section that receives the beam reflected from the disc and converts it into an electrical signal; and a control section for determining the values of a first group of parameters, which are set to read data from the first layer (L0), and those of a second group of parameters, which are set to read data from the second layer (L1), during a disc loading process. In performing the disc loading process, the control section determines the values of the first group of parameters, and then determines the values of the second group of parameters based on correlation information, representing correlation between the values of the first and second groups of parameters that were set during a previous disc loading process, and on the values of the first group of parameters that have been just determined during the current disc loading process.

摘要： A wireless transmitter and receiver increase a desired/unwanted (D/U) ratio of a correlation output without increasing the number of data in an ultra-wideband direct spread pulse communication system for transmitting and receiving two series of data through different spreading code streams. In the spreading codes used in matched filters of the wireless transmitter, (2*N−2)-th and (2*N)-th values of a cross-correlation signal between first and second spreading codes are greater than 0, (2*N−3)-th and (2*N+1)-th values of an auto-correlation signal of the first spreading code are less than 0, and (2*N−3)-th and (2*N+1)-th values of an auto-correlation signal of the second spreading code are less than 0. The peak value of the cross-correlation signal does not need to be small, and since a value other than the peak value does not become large, the D/U ratio can increase.

摘要： A complex coefficient transversal filter using a SAW filter and a complex frequency converter using the complex coefficient transversal filter are provided, in which a first SAW filter receives a real signal as an input signal and generates a real component of a complex signal, and a second SAW filter receives the real signal as an input signal and generates an imaginary component of the complex signal. Accordingly, feed-through waves between the input and output stages can be cancelled, and a phase difference between real and imaginary signals can be maintained at 90° without a phase shift. In addition, when a low-IF frequency converter is implemented using the complex coefficient transversal filter, an image suppression characteristic is improved. When a zero-IF frequency converter is implemented using the complex coefficient transversal filter, an error vector magnitude (EVM) characteristic is improved.
