Blind Symbol Timing Recovery for Multi- Level/Multi-h CPM signals with High Spectral Efficiency

Abstract ─ In this paper, symbol timing recovery for con-tinuous phase modulated signals is investigated making use of a new method that exploits the received signal’s cyclostationar-ity. This algorithm can be employed with either full or partial response signalling in the form of an open-loop estimator. Per-formance in terms of estimation error variance and bias is as-sessed by analysis and simulation. I
