摘要： The present invention relates to a multi-antenna digital receiver comprising receiving antenna elements, an ADC unit which receives input signals, and a DSP unit. The ADC unit determines, for each input signal a corresponding discrete-time folded signal by applying a modulo operation to the input signal or to a function thereof, and generates a quantized signal based on the discrete-time folded signal. The DSP unit comprises a joint reconstruction block, which jointly processes the quantized signals or a subset thereof to generate output signals. Each of the output signals is a digital representation of a linear combination of the discretetime folded signals. A digital control block in the DSP unit generates a control signal for controlling the modulo operation and determines the coefficients of the linear combinations to maximize a utility function measuring a QoS of a communication between a transmitter connected to the digital receiver and the digital receiver.

摘要： A modulo-based analog-to-digital conversion, ADC, implementation relating to the field of signal processing is disclosured. The modulo-based ADC implementation disclosed herein involves converting an input analog signal into phases of other M periodic analog reference signals based on one or more transfer functions, wherein M≥2. The phase of each of the M reference signals comprises a folded signal corresponding to the input analog signal that is amplitude-folded to fall within a required amplitude range. This signal-to-phase conversion allows a modulo operation to be implemented over the input analog signal. Further, the M reference signals are used to obtain M discrete-time digital signals which, in turn, are used to obtain a digital representation of the input analog signal.
