Symbol and superbaud timing recovery in multi-H continuous-phase modulation

This letter is concerned with the estimation of two synchronization paramet ers that play a key role in multi-h continuous-phase modulation receivers-t he ordinary symbol timing phase and the so called superbaud timing phase, T he recovery of symbol and superbaud timing is implemented by means of feedf orward nondata-aided algorithms. The novelty of the proposed method is that it can be applied to any modulation format, either full or partial respons e, with binary or muitilevel symbols and with arbitrary modulation indices.
