Better Satellite Link Distortion Testing Using Spectral Correlation Method
應用說明
Like ground-based systems, the capacity and complexity of space-based communications is growing exponentially. System designs are being pushed to their limits as the need for greater capacity leads to faster data rates and higher bandwidths. As always, signal power is a key metric, and the need for more power across wider channels means that power amplifiers spend more time inside their nonlinear operating region. The result of this is signal distortion, and systems designers need to find ways to either reduce this distortion or work around it. Making accurate, insightful measurements of this distortion is the first step in solving the problem.
