Higher-order Multilevel Signal Transmission using Coherent Receiver with Digital-Delay Detection

Not Accessible

Your library or personal account may give you access

Abstract

The use of digital-delay detection for coherently received higher-order QAM signals is an attractive technique to improve phase noise and IF offset tolerance. The paper reviews its concept, implementation and performance improvement with experimental results.
