Patent number: 11329678Abstract: A receiver system includes an interface between a radio receiver on a radio frequency (RF)-side and a baseband receiver on a baseband (BB)-side. The receiver includes an antenna for receiving radio frequency signals and an analogue-to-digital converter for converting received analogue signals to digital signals. The digital signals are further processed in the baseband receiver by a digital signal processing unit. The analogue-to-digital converter is a sigma-delta converter, which includes a sigma-delta modulator on the RF-side and a decimation filter on the BB-side. The sigma-delta modulator and the decimation filter are connected only by single-bit in-phase (I) and quadrature (Q) streams output lines.Type: GrantFiled: August 21, 2018Date of Patent: May 10, 2022Assignee: COMMSOLID GMBHInventor: Andreas Bury

Patent number: 8731038Abstract: A mobile station receiving a signal from a base station experiences time/frequency varying channel conditions. In order to get the maximum throughput from a base-station, it is necessary to adjust the modulation and coding schemes to the actual channel quality. To do so, mobile receivers are required to probe the radio channel condition and feedback a limited set of estimated channel state information parameters such as CQI, RI, and PMI. The invention uses modulation-specific mutual information as a basic metric for CQI-PMI-RI computation to yield high bandwidth efficiency under both flat fading and interference conditions as well as time and frequency selective fading and interference conditions, at reasonable complexity.Type: GrantFiled: July 9, 2012Date of Patent: May 20, 2014Assignee: Intel Mobile Communications Technology Dresden GmbHInventors: Johan Pean, Andreas Bury

Patent number: 8611443Abstract: Orthogonal frequency division multiplexing (OFDM) has become a popular transmission method for high speed wireless radio transmission, due to its potential for low complexity of transmitters and receivers. A method and apparatus are contemplated for cancelling additive sinusoidal disturbances of a known frequency in OFDM receivers which arise e.g. from clock signals that are present for frequency reference, mixer control, and A/D converter control, as well as harmonics and mixing products of those periodic signals, coupling into some point in the receiver chain and appearing as rotating complex exponentials superimposed to complex baseband receive signals. According to the inventive method and apparatus an estimation of an amplitude and phase of a disturbing superimposed tone with a known frequency is obtained and the amplitude and phase estimation is used to cancel the spurious tone preventing a degradation of receiver sensitivity while achieving low implementation complexity.Type: GrantFiled: January 15, 2009Date of Patent: December 17, 2013Assignee: NXP, B.V.Inventor: Andreas Bury
