About Ultra-Wideband DesignGuide

The Ultra-Wideband DesignGuide test benches provide rapid setup, analysis, and simulation results to verify the most common performance characteristics of UWB transmitters and receivers. Bi-phase and pulse-position UWB modulation and formats are supported.

Simulation results provide information for spectral characteristics and basic bit-error-rate versus signal-to-noise ratios, as well as environmental effects such as multi-path and propagation loss, allowing the BER to be determined as a function of range. Simulations also evaluate rake receiver performance in a multi-path environment and synchronization of a UWB correlator. Effects of narrowband and wideband interference on UWB system performance can also be evaluated.

The UWB DesignGuide requires the ADS Ptolemy (signal processing simulation) and dg_ultrawideband licenses in addition to the ADS design environment license. The Analog/RF linear simulator can be used to generate S-parameter files for antennas, but is not required. S-parameter files can be obtained via network analyzer measurements or other sources.

Features and contents of the UWB DesignGuide are accessible from the DesignGuide menu in an ADS Schematic window. Selecting a test bench copies a schematic into the current project and opens a Data Display window.

Hints regarding this DesignGuide Information about items in a Data Display window that you would want to modify is outlined in red. Equations that you typically do not need to modify are often included in a separate Equations page. After selecting an item that opens Schematic and Data Display windows, if you re-name the schematic and run a simulation, to display your latest simulation results open the data display file that corresponded to the original schematic, change the default dataset name (typically the same as the new name of your schematic).
