摘要： An antenna array (10) for the transmission of signals (20) is disclosed. The antenna array (10) comprises: a plurality of transmission paths (30-1, 30-2, 30-K) for transmitting a plurality of wanted signals (25) and at least one calibration signal generator (40-1, 40-2, 40-K) for the generation of at least one calibration signal (45). A plurality of calibration signal mixers (50-1, 50-2, 50-K) mixes the at least one calibration signal (45) with the plurality of wanted signals (25) to produce a plurality of transmission signals (20). A path sum signal device (60) sum the plurality of transmission signals (20) to produce a summed transmission signal (65); and an interference estimator (90) accepts the at least one calibration signal (45) and generates an estimated interference signal (92). An estimation signal mixer (95) subtracts from the summed transmission signal (65) the estimated interference signal (92) to produce a difference signal (97); and a on signal detection unit (70) for comparing the signal (97) with the at least one calibration signal (45).

摘要： Transmitter comprising a delta-sigma modulator (DSM), a sample rate converter (SRC) situated downstream of the delta-sigma modulator with respect to a direction of transmission signal flow, and a switching amplifier (SA) situated downstream of the sample rate converter (SRC) with respect to the direction of transmission signal flow. The invention as defined above allows for a decoupling of the clock frequency of the delta-sigma modulator (DSM) and the carrier frequency, for example in radio frequency (RF) signal generation applications using delta-sigma modulators. With the invention described herein it is possible to design the delta-sigma modulator independently of the carrier frequency.

摘要： The present disclosure teaches a calibration system, a calibration apparatus and a method for calibrating a signal path and a method for calibrating a delay. The calibration system comprises an injector, a calibration signal generator, a correlator, a detector unit, a polygon former and a pattern classifier unit. The calibration system is adapted to calculate a fraction of a delay from a set of polygons. The delay is being accumulated along a signal path. The fraction of the delay is indicative of an accuracy of the delay at a fine sampling rate as if the delay was measured at the fine sampling rate being an integer multiple of the coarse sampling rate. The method for calibrating of the signal path uses a calibration signal sampled at a coarse sampling rate. Correlation techniques are used in order to detect a fraction of the delay from a set of polygons.
