Challenge: Developing an improved method for digitally correcting software impairments using mathematical algorithms, and validating the approach using real-world wireless signals.
Solution: Migrating simulation-only code to NI LabVIEW software and using real-time digital signal processing (DSP) with two NI USRP™ (Universal Software Radio Peripheral) software defined radios to specifically address nonlinear amplifier impairments and validate algorithms with real-world signals.
