BER Estimation for Multilevel Modulation Formats

Not Accessible

Your library or personal account may give you access

Abstract

We review existing BER estimation methods and propose alternative methods to assess the performance of multilevel modulation formats with both direct and coherent detection. The impact of digital signal processing (DSP) on the BER estimation procedure is discussed for the latter case. The different approaches are illustrated by simulating exemplary transmission systems.
