Timing Synchronization for Upstream Cable OFDMA Signals
2019 Edition, August 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The most recent broadband data-over-cable standard, known as DOCSIS 3.1, introduced orthogonal frequency-division multiplexing (OFDM) as a major upgrade to improve transmission efficiency. Because OFDM signals are sensitive to synchronization errors, accurate timing...

Comparison of Feedforward Synchronization Schemes for Full-response CPM Signals
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We compare three non-data-aided synchronization techniques for full-response continuous phase modulation (CPM) signals, which have feedforward structures and are suitable for burst-mode transmissions. All the schemes are based on the statistical characteristics of the...
