Simulate, analyze, and test the physical layer of LTE and LTE-Advanced wireless communications systems
LTE Toolbox™ provides standard-compliant functions and apps for the design, simulation, and verification of LTE, LTE-Advanced, and LTE-Advanced Pro communications systems. The system toolbox accelerates LTE algorithm and physical layer (PHY) development, supports golden reference verification and conformance testing, and enables test waveform generation.
With the toolbox you can configure, simulate, measure, and analyze end-to-end communications links. You can also create and reuse a conformance test bench to verify that your designs, prototypes, and implementations comply with the LTE standard.
Using LTE Toolbox with RF instruments or hardware support packages, you can connect transmitter and receiver models to radio devices and verify your designs via over-the-air transmission and reception.
