چکیده
Fig. 1 The R&S®FSW26 signal and spectrum analyzer with the R&S®FSW-K17 multicarrier group delay measurement option. The combination of low phase noise, large analysis bandwidth and state-of-the-art user interface makes the R&S®FSW a unique measuring instrument in its class. Equipped with the R&S®FSW-B160 analysis bandwidth extension, group delay measurements up to a bandwidth of 160 MHz can be performed. Multicarrier method and its impressive characteristics Detecting amplitude and phase distortions is crucial to characterizing the quality of a transmission path. The reason: Signal deformations resulting from these distortions are directly linked to a deterioration of the signal-to-noise ratio (SNR) and an increased bit error rate at the receiver end.

Wideband Dispersion Analysis of Waveguide Geometries Using Finite Sampled Data
Wideband analysis of frequency dispersive geometries is a challenge in inverse scattering problems. Waveguide duct is an important case in aerial targets with dominant returns. Its dispersive behavior affects the range profile analysis due to occurrence of unwanted range extension. A new high frequency analysis using model based parameter estimation (MBPE) approach is presented. A group delay c...
متن کاملGeneration of WDM adaptive-rate pulse bursts by cascading narrow/wideband tunable optical dispersion compensators.
We demonstrate passive generation of optical pulse trains with each pulse having distinct center carrier and spectra using tunable group delay (GD) staircase transfer functions. The GD steps result from opposite and equal magnitude GD slopes from narrowband and wideband tunable optical dispersion compensators. We use this technique to split the spectrum of a femtosecond pulse to a pulse burst w...
متن کاملOptimization of a Wideband Tapped-Delay Line Array Antenna
In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

متن کاملWideband Measurements of Angle and Delay Dispersion for Outdoor and Indoor Peer-to-Peer Radio Channels at 1920 MHz
This paper presents spatio-temporal measurements for the peer-to-peer radio channel at a center frequency of 1920 MHz with 140 MHz of radio-frequency bandwidth. The measurements were taken using a spread-spectrum channel sounder and an automated spatial probing system that uses precise computer-controlled positioning and orientation of omnidirectional and directional (30 beamwidth) antennas to ...
