Patent number: 7215726Abstract: A method for interference suppression for TDMA and/or FDMA transmission, which at least approximately can be described as pulse amplitude modulation, with an arbitrary number of receive antennas. The method comprises filtering of at least one complex-valued received signal ri[k] of one receive antenna with a filter with complex-valued coefficients fi[k] for generation of at least one output signal yi[k], forming at least one projection of at least one output signal yi[k] onto a vector pi which is assigned to this output signal yl [k], summing of a majority, especially all of the output signals yi[k] for forming a sum signal s[k], and feeding the sum signal s[k] into a device for detection, especially equalization. A system for interference suppression for TDMA and/or FDMA transmission is also disclosed.Type: GrantFiled: December 19, 2001Date of Patent: May 8, 2007Assignee: Com-Research GmbHInventors: Raimund Meyer, Robert Schober, Wolfgang Gerstacker

Publication number: 20070046369Abstract: A method and apparatus for an ultra-high sensitivity, low cost, passive (no battery) low-power energy harvesting data transmitting circuit energy, such as a RFID (Radio Frequency IDentification) tag integrated circuit “chip.” By using combinations of special purpose design enhancements, the low-power energy harvesting passive data transmitting circuit, such as the RFID tag chip, operates in the sub-microwatt power range. The chip power should be derived from a low-microwatt per square centimeter RF field radiated to the RFID tag antenna from the tag reader (interrogator) or derived from a suitable low signal source, such as a sonic transducer (e.g., a piezoelectric transducer or a low level DC source, such as a bimetallic or chemical source).Type: ApplicationFiled: July 22, 2006Publication date: March 1, 2007Inventors: Robert Schober, Ion Opris, Francois Krummenacher

Publication number: 20050069066Abstract: The present invention relates to a method and a system for estimation of the frequency offset in the digital transmission which is applicable for arbitrary linear modulations, dispersive channels, and general additive impairments. In a first step of the method N derivatives of the received signal are formed through discrete frequency shifts. Subsequently, these derivatives are preprocessed and equalized in an appropriate manner. On the basis of reliability information about the corresponding reconstructed symbol sequences, which is given in the form of metrics Mv which are obtained from internal variables of the equalizer (in case of hard-output equalization) or its output values (in case of soft-output equalization), an estimate of the frequency offset can be established by analysing them in connection with the N corresponding frequency shifts fv. Herein it is to be noted that the N equalizations do not necessarily have to equalize the entire received signal, but only part thereof.Type: ApplicationFiled: November 13, 2002Publication date: March 31, 2005Inventors: Raimud Meyer, Robert Schober, Wolfgang Gerstacker

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
