摘要： The present invention discloses an optical drive and a method for preprocessing a disc readout signal r k of an optical drive on the basis of a set of low-pass filters. The cutoff frequency f c of the filters wk, more particularly, can be set within the optical bandwidth, which improves the Viterbi detection performance in the case of high speed drive operations. Three types of filters are described, in which a Type I shaping filter performs best given a limited hardware cost for the bit detector. Compared to other more advanced noise- whitening techniques, it is only speed dependent and requires little prior knowledge of the channel and noise, thus cheap and easy to design. The invention can be applied in connection with optical disc drives, in particular when high frequency noises are dominant, for example, in the case of high speed operations.

摘要： A loss of performance of slicer adaptation at high capacities due to the mismatch between the exact bits used in the computation of the RDS for the DC-control on the one hand and the often erroneous threshold decisions that are preliminarily made based on the HF waveform on the other hand, is resolved by performing a new method of DC- control at the encoder: the RDS is modified such that it is not based on the exact channel bits, but on the threshold decisions from a synthetic HF signal waveform that is generated based on a nominal MTF (modulation transfer function) or its IRF (impulse response function) of the channel. In this way, the impact of the erroneous threshold decisions in the receiver are already taken into account at the encoder, and the slicer control is no longer negatively affected thereby.

摘要： ABSTRACT: In modem optical disc systems, inter-track spacing is chosen relatively small in order to allow high storage densities. As a result, the optical spot has a radius comparable with the track pitch, and the data written on neighboring tracks appear in the target track signal in the form of inter-track interference (cross-talk). To tackle the cross-talk problem, cross-talk canceling schemes are normally employed. These schemes use three spots, one spot on the main track and two satellite spots on adjacent tracks. The read signal (C) is improved by minimizing the cross-talk between the satellite signals (S + ,S - ) and the read signal (C). However, due to the decreasing inter-track spacing, the decorrelation concept fails since the satellite spots read too much central track information and become strongly correlated with the read signal (C), which causes "leakage" in the decorrelation. The present invention solves this problem with an additional circuit for outputting improved satellite signals ( Š + , Š - ) which circuit suppresses cross-talk of the main track present in the satellite signals (S + ,S - ) by minimizing a correlation between the satellite signals (S + ,S - ) and the read signal (C), the improved satellite signals ( Š + , Š - ) being subsequently fed to the first circuit which is arranged to suppress the cross-talk of the read signal (C) by minimizing a correlation between the improved read signal ( Č ) and the improved satellite signals ( Š + , Š - ).

摘要： The invention relates to a device and a method for determining a direction of movement (DOM) of a person carrying a portable acceleration sensor. The direction of movement (DOM) characterizes the motion direction of the person' s movements at certain points in time. By utilizing that the person's movement in directions other than the direction of movement (LAT) averages to zero over a given time interval, the forward direction of movement can be determined. The direction of movement (DOM) can be determined under the constraint of minimizing the displacements in a direction perpendicular to the direction of movement or by ensuring that the accumulated displacement perpendicular to the direction of movement (LAT) approximates (LAT) zero or is below a given threshold value.

摘要： The invention relates to an apparatus (20) for reading data from and/or writing data onto an optical data carrier (21) is proposed. An optical source generates an incident beam (26), an objective lens assembly (28) focuses the incident beam onto the optical data carrier. A thin convex lens (32) without substantial astigmatism is used for projecting the returning beam (30) onto an optical detection assembly (33) for generating a tracking error signal. An optical data carrier has a recording layer, onto which optically readable data is written in the form of binary marks or pits (11). The binary marks are capable of causing a phase difference which lies close to 180° between reflected light which has interacted with said binary marks and reflected light which has interacted with the rest of the recording layer. The signal to noise ratio of data signal and tracking error signal are improved at the same time.

摘要： The invention relates to Run length Limited-codes storage systems. In modern storage systems, the inter-track spacing is chosen to be relatively small to allow for high storage densities. As a result, when reading a target track, data written on side tracks may appear in the recovered signal. This inter-track interference is called cross-talk. The invention proposes a cross-talk cancellation scheme based on the minimization of the mismatch between the actual (dm+1m) and the expected (exp) run length between two transitions (xm, xm+1) of the (dm+1,m) signal. The proposed solution significantly improves the ramp-up properties of the receiver and allows more efficient hardware implementation.

摘要： A signal processing technique is proposed for compensating for radial to focus crosstalk in an optical storage system including an astigmatic lens (25) and four-quadrant photodetector (26) for generating a focus error signal. A signal processor generates the focus error signal (FES RVO ), a tracking error signal (TES) and a central aperture signal (CA) and the proposed radial and focus crosstalk scheme can be described by the following equation (I): Where IFES Rvo represents the improved focus error signal and y 1 j and y 2 j are vector components for scaling. Instead, scalar adaptive scaling factors γ 1 and γ 2 may be applied which can be updated by minimising a cost function J(y 1 ,y 2 ), which is able to imply the radial to focus crosstalk components remaining in the focus error signal.
