In this paper, we present a method to limit the generation of signal peak power at the output of a digital pre-distorter that is applied to a RF power amplifier (PA) operating in strong compression. The method can be considered as a joint crest-facto

In this paper, a prototype setup for measuring wideband periodic waveforms whose bandwidth surpasses the analog bandwidth of a radio-frequency receiver is presented. Three major challenges arise in the analog-to-digital stage when measuring such wide

The general approach for modeling systems assumes that the measured signals are (weakly) stationary, i.e., the power spectrum is time invariant. However, the stationarity assumption is violated when: 1) transient effects due to experimental condition

In this paper, a method for measuring wideband waveforms correctly when undersampling is used as a digitizing technique is presented. Two major challenges arise when undersampling wideband waveforms: overlapping of aliased spectral bins of the digiti

The bit-error-rate (BER) estimation of communication systems can be very time consuming when dealing with complex communication systems and complex modulation schemes such as orthogonal frequency-division multiplexing (OFDM). The signals of such modu

Classical calibration techniques use single-sine-wave measurements to maximize the signal-to-noise ratio (SNR). In large-signal characterization, the large number of instrument states to be calibrated results in unacceptably long calibration times. T

In this paper, a method to determine the reciprocity of radio-frequency mixers is proposed based on fully calibrated three-port large signal network analyzer measurements. Besides revealing the reciprocity of the mixers, this type of measurement can

Extracting quantities, such as the propagation factor or the characteristic impedance of a transmission line based on measured S-parameters, can be more involved than expected. Experience teaches that even if the S-parameter measurements look smooth
