Comparison of Multisine Measurements from Instrumentation Capable of Nonlinear System Characterization
نویسندگان
چکیده
We compare measurements of simple multisines using instruments capable of characterizing both magnitude and relative phase of the measured signals. The three instruments we compared reported relative phase measurements within a few degrees of each other with a standard deviation of less than a degree at microwave frequencies for both wide and narrow modulation bandwidths. Key Words—digital sampling oscilloscope, vector signal analyzer, sampling waveform analyzer, timebase correction, phase detrending, multisine, wireless systems

An efficient nonlinear least square multisine fitting algorithm
This paper presents a new nonlinear least-squares algorithm for fitting band-limited periodic signals with unknown frequency and harmonic content. The new solution features a model-based recursive calculation method that requires less memory space and has smaller computational demand than the known matrix-based algorithms.
متن کاملImpact of nonlinear friction on frequency response function measurements
This paper discusses the impact of nonlinear friction on frequency response function (FRF) measurements of mechanical systems with nonlinear friction. Having an idea of the level of nonlinear distortion is valuable information for robust linear control design: it allows to estimate the level of accuracy of a linear approximation of the system under consideration. The impact of nonlinear distort...
متن کاملWaveform Optimization for SWIPT with Nonlinear Energy Harvester Modeling
Abstract—Simultaneous Wireless Information and Power Transfer (SWIPT) has attracted significant attention in the communication community. The problem of waveform design for SWIPT has however never been addressed so far. In this paper, a novel SWIPT transceiver architecture is introduced relying on the superposition of multisine and OFDM waveforms at the transmitter and a power-splitter receiver...
متن کاملSequential Multisine Excitation Signals for System
Linear system identification of complex nonlinear systems, such as large space structures, can be difficult because such systems are often lightly damped, have dense modal spacing, respond to disturbances over a large frequency bandwidth, and exhibit nonlinear responses. Many excitation signals used to collect frequency response data for linear system identification are poorly suited to systems...
متن کاملMultisine Signals for Wireless System Test and Design
122 June 2008 Multisine signals are used in the laboratory and in the field to provide a periodic, well-characterized waveform that can simulate complex modulated radio frequency (RF) signals. For example, in the field of wireless telecommunications, multisines are often used to provide realistic test signals that have statistics similar to various types of digitally modulated signals. Multisin...
