test and measurement -凯发k8网页登录

describes waveform generation, visualization, and transmitter performance analysis

lte toolbox™ provides functions that let you measure transmitter performance characteristics. the examples featured here demonstrate transmitter modeling and performance analysis. communications toolbox™ and dsp system toolbox™ system objects provide additional quantitative tools for measuring system performance, and graphical utilities for visualizing waveforms.

topics


  • the lte specifications define conformance test models for transmitter tests.


  • this example shows how to configure and use the block that is generated using the export to simulink capability that is available in the wireless waveform generator app.
