The Multipath Fading Emulator (MFE) is a Skytechnology software product developed to emulate the selective fading due to multipath propagation on microwave radio paths.

The MFE works with the NI PXIe-5646 PXI Vector Signal Transceiver (VST), a single device that combines a vector signal analyzer and vector signal generator with a user-defined FPGA.

The MFE implements the “Two-Rays” channel model using a custom FPGA configuration for the VST. You can simulate the effect of multipath propagation on the RF channel by (1) controlling directly the frequency and depth of the notch introduced by the channel model or (2) setting a different fractional delay of the interfering ray. You can vary all impairments parameters (notch frequency and depth, flat fading, second path delay) with a user-defined slew rate to make them automatically loop in a user-defined range of values with the set slew rate.

The MFE architecture adheres to the underlying hardware: signal acquisition, processing, and generation are carried on an FPGA, while system/test configuration and HMI are managed at a higher level on an integrated PXI controller.
