Publication number: 20080232213Abstract: On existing DVD and CD players a control loop is required for the adaptation and timing recovery. For Two-Dimensional Optical Storage such a control loop has drawbacks because PRML detection in the form of a stripe-wise Viterbi detector is used. Such a detector introduces an increasing detection delay when going from the outer rows towards the center of the broad spiral. A feedback loop is arranged to determining an error signal from a first area of the data block where the first area is that area where the error signal can be determined within the shortest period of time. This reduces the duration of the detection step and thus increases the stability of the control loop.Type: ApplicationFiled: January 24, 2005Publication date: September 25, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONIC, N.V.Inventors: Johannes Wilhelmus Maria Bergmans, Albert Hendrik Jan Immink, Jamal Riani, Willem Marie Julia Marcel Coene, Steven Jena-Marie Lucie Van Beneden, Massimo Ciacci, Ali Nowbakht Irani

Patent number: 7206349Abstract: Described is a transmission system for transmitting a multicarrier signal from a transmitter (10) to a receiver (20). The multicarrier signal comprises a plurality of subcarriers. The receiver (20) comprises a channel estimator (28) for estimating amplitudes of the subcarriers and for estimating time derivatives of the amplitudes. The receiver (20) further comprises an equalizer (24) for canceling intercarrier interference included in the received multicarrier signal in dependence on the estimated amplitudes and derivatives (29). The channel estimator (28) and/or the equalizer (24) are arranged for exploiting an amplitude correlation between the derivitives of different subcarriers. By making use of this correlation the complexity of the receiver (20) can be substantially reduced.Type: GrantFiled: February 22, 2001Date of Patent: April 17, 2007Assignee: Koninklijke Philips Electronics N.V.Inventors: Johan Paul Marie Gerard Linnartz, Alexei Gorokhov, Johannes Wilhelmus Maria Bergmans, Antonius Adrianus Cornelis Maria Kalker

Publication number: 20040156293Abstract: Domain bloom, also known as asymmetry, is a systematic imperfection caused by the writing process in optical discs. During disc read-out it causes signal transitions to shift with respect to their nominal positions. State-of-the-art equalization and detection methods suffer significant performance losses if directly applied to replay signals with asymmetry. A non-linear model for replay signals with asymmetry is used for new equalization and detection techniques that are applicable to signals in the presence of asymmetry. Modifications are described of the threshold bit-detector, the run-length pushback bit-detector, and the PRML sequence detector, which have significant performance benefits. These benefits come at almost no additional cost with respect to existing detectors.Type: ApplicationFiled: December 9, 2003Publication date: August 12, 2004Inventors: Charalampos Pozidis, Willem Marie Julia Marcel Coene, Johannes Wilhelmus Maria Bergmans

Patent number: 6731699Abstract: A detector (30) is described for detecting a digital signal (Bio) out of an input information signal (Ai) which represents a runlength limited sequence, the runlength having a minimal value m. The detector (30) generates (60, 62) a preliminary binary signal (Bi) out of the input information signal (Ai). A composed sequence of subsequent bits is identified (86) within the preliminary binary signal (Bi) which subsequently includes at least a first neighboring bit of a run of length greater or equal than m+1, one or more further runs of length m and at least a second neighboring bit of a run of length greater or equal than intl. A set of sequences are generated (84, 86). These sequences can be obtained from said composed sequence by changing polarities of binary values within the composed sequence without violating the runlength constraint. The set includes the composed sequence obtained from the preliminary binary signal.Type: GrantFiled: May 18, 2001Date of Patent: May 4, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Charalampos Pozidis, Willem Marie Julia Marcel Coene, Johannes Wilhelmus Maria Bergmans

Publication number: 20030028839Abstract: The invention relates to methods and devices for converting a stream of data bits of a binary information signal 2 into a stream of data bits of a constrained binary channel signal 3 using multiple channel codes Cst, Cpc. Apart from a standard code Cst, that is designed for a high coding rate, a parity-check enabling code Cpc is used that allows realization of a certain, predefined parity-check constraint imposed on the constrained binary channel signal 3. This parity-check constraint is related to a predetermined error event of the channel. The amount of use of the parity-check enabling code Cpc is dependent on the need for preventing the certain error event. Also another channel code Csub can be used in this method in order to realise DC-control.Type: ApplicationFiled: April 1, 2002Publication date: February 6, 2003Inventors: Willem Marie Julia Marcel Coene, Charalampos Pozidis, Johannes Wilhelmus Maria Bergmans

Patent number: 6515812Abstract: A new embedded-servo format is proposed for use in disk drives, preferably hard disk drives. It is based on biphase modulation (more generally, p-phase modulation, where p>1) and offers significant advantages, in terms of SNR and timing content, over existing formats. It is shown that for biphase, at the low linear densities typically employed for servo information, near maximum-likelihood performance may be attained by a simple bit-detector consisting of a full-response linear equalizer and a binary slicer. When compared with an optimal detector for the commonly used technique of dibit signalling, a SNR gain of some 4 dB is achieved. The same equalizer may be used as the basis for near-maximum-likelihood Position Error Signal (PES) amplitude estimation and timing recovery. Investigations carried out on a practical servo demodulator based on a 5th order analog filter show that, at typical linear densities, this ideal performance is closely approached.Type: GrantFiled: April 20, 2000Date of Patent: February 4, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Johannes Wilhelmus Maria Bergmans, Kofi Afolabi Anthony Makinwa, Johannes Otto Voorman
