Patent number: 7979273Abstract: The invention is based on the idea of providing a method for high-resolution, waveform-preserving digitization of analog signals, wherein conventional scalar logarithmic quantization is transferred to multi-dimensional spherical coordinates, and the advantages resulting from this, e.g., a constant signal/noise ratio over an extremely high dynamic range with very low loss with respect to the rate-distortion theory. In order to make use of the statistical dependencies present in the source signal for an additional gain in the signal/noise ratio, the differential pulse code modulation (DPCM) is combined with spherical logarithmic quantization. The resulting method achieves an effective data reduction with a high long-term and short-term signal/noise ratio with an extremely small signal delay.Type: GrantFiled: July 23, 2004Date of Patent: July 12, 2011Assignees: Sennheiser electronic GmbH & Co.

Publication number: 20050111347Abstract: In a transmitting/receiving concept a redundancy-adding encoder with a code rate larger or equal 0.5 is used in order to obtain two data streams for two different transmitters which are arranged at spatially different positions. Both transmitters transmit in the same frequency band. In the receiver, the receiving signal is sampled by a first sampler synchronous to the first transmitter and is output by a second sampler synchronous to the second transmitter in order to obtain a first and a second receiving signal which are fed to a trellis decoder in order to obtain a decoded first and second receiving subgroup of code units which are again fed to a calculating means in order to calculate the interference signals which are then combined with the corresponding receiving signals for an interference reduction. The iterative concept enables an interference reduction for receiving signal generated by two spatially separated transmitters which are transmitting in the same frequency band, however.Type: ApplicationFiled: November 10, 2004Publication date: May 26, 2005Inventors: Marco Breiling, Johannes Huber, Alexander Lampe, Ernst Eberlein

Patent number: 6618452Abstract: Carrier frequency and frames are synchronized in bursty data transmissions over unknown channels that cause inter-symbol interference. The synchronization procedure comprises two stages. The first stage performs a time-domain processing of samples to exploit a periodic signal repetition and to extract the coarse timing, the frequency offset and also to resolve frequency ambiguities. The second stage estimates the fine time offset of a received modulation signal. A coarse estimate of a frame start position of a received sequence of desired data samples may be improved by using the coarse timing estimate to generate frequency-domain received samples. A frequency-domain correlation is then determined between the frequency-domain received samples and noiseless samples. When using a fixed number of training samples, a “sandwich” preamble (“sandamble”) is utilized to achieve greater efficiency than a conventional repetition preamble.Type: GrantFiled: April 27, 1999Date of Patent: September 9, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johannes Huber, Stefan Müller-Weinfurtner

Patent number: 6608873Abstract: Demodulation of CPM-modulated information symbols which are demodulated after being transmitted through an AWGN channel, using only partial whitened matched filtering, whereby finite pulses are produced which, however, are still accompanied by interferences in the form of remaining colored noise which can be approximately converted into white noise by a successive additional whitening filter so that the noise power will be minimized. For correcting the accompanying symbol interferences, a sequence estimation with reduced number of states follows.Type: GrantFiled: February 25, 1999Date of Patent: August 19, 2003Assignee: Siemens Mobile Communications S.p.A.Inventors: Bernhard Spinnler, Berthold Lankl, Johannes Huber

Patent number: 6442211Abstract: The system achieves high bandwidth efficiency and a low bit and message error probability in digital data transmission. The system, with its associated methods and devices, obviates carrier synchronization or clock synchronization. Digital multicarrier transmission with coding and decoding is carried out on the basis of block synchronization, wherein, for carrier modulation, the modulation of the subcarriers is carried out differentially in coded form in the direction of the subcarriers, that is to say in the frequency domain.Type: GrantFiled: March 22, 1999Date of Patent: August 27, 2002Assignee: IAD Gesellschaft für Informatik, Automatisierung und Datenverarbeitung mbHInventors: Herrmann Hampel, Johannes Huber, Klaus Lehmann, Thomas Wagner

Patent number: 6345076Abstract: The invention relates to a receiver for a digital transmission system with an incoherent transmission method, which receiver includes an equalizer for forming estimates for a sequence of symbols a[k] transmitted by a transmission channel from received symbols r[k] by means of an impulse response h[k] that describes the transmission properties. For improving the receiving quality in an incoherent transmission method and transmission channels having intersymbol interference, it is proposed that the equalizer performs an incoherent maximum likelihood sequence estimation (MLSE) method to determine the estimates â[k] for the sequence of transmitted symbols a[k]. In channels having intersymbol interference, the incoherent MLSE method provides clearly better results than all the known incoherent receiving methods. As against frequency and phase offset, the incoherent MLSE method is considerably more robust than all the known coherent receiving methods.Type: GrantFiled: April 26, 1999Date of Patent: February 5, 2002Assignee: U.S. Phillips CorporationInventors: Jürgen Petersen, Robert Schober, Wolfgang Gerstacker, Johannes Huber

Patent number: 6125103Abstract: The major problem in multicarrier transmission procedures consists in the very high crest factor of the transmit signal. This means, that very high signal peak values occur even with a moderate transmission power. It is the object of the invention to provide a method and device, whereby a definite reduction of signal peaks is achieved with moderate expenditure. This is obtained by generating, in addition to the information to be transmitted, several alternative, information-equivalent information sequences by means of determined reversible unambiguous representations. From these alternatives a sequence being favorable in view of the peak value of the pertinent transmit signal is selected and transmitted. The receiver is in a position to regenerate the original information from said receiving signal through the inversion of the performed representation.Type: GrantFiled: September 3, 1997Date of Patent: September 26, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Robert Bauml, Robert Fischer, Johannes Huber, Stefan Muller

Patent number: 6118816Abstract: The invention relates to a digital transmission system comprising a receiver, in which system a trellis-based estimation method (3) with a number of states reduced as a result of feedback (5) of at least one feedback value (.xi.) forms estimates (a) for a received signal (r) by means of an estimated impulse response (h) of a transmission system (1), a feedback value (.xi.) being determined from at least one estimate (a). With reduced-state estimation methods for the digital transmission, the problem consists of the additional noise components caused by the feedback of preliminary false symbol decisions. To achieve optimum estimates (a) for the received signal (r) despite a reduced number of states due to feedback, the receiver forms the feedback value (.xi.) from at least one intermediate value (a.sub.SDF). In digital transmission systems, the transmit symbols (a) and the estimates (a) have the values -1 or 1 in the receiver. In the receiver according to the invention, intermediate values (a.sub.Type: GrantFiled: November 12, 1997Date of Patent: September 12, 2000Assignee: U.S. Philips CorporationInventors: Raimund Meyer, Stefan Muller, Wolfgang Gerstacker, Johannes Huber
