In this context, feedforward algorithms are particularly helpful in packet\u2010oriented systems, where rapid and stable acquisition of the major transmission parameters is essential for subsequent processing stages. On the other hand, feedback algorithms are typically used to track small deviations from the stable equilibrium point. In the current paper, we propose a new approach for blind feedforward and feedback recovery of the symbol timing, which needs just one or two samples per symbol. The method is characterized by a second filter operated in parallel to the receiver\u2010matched filter. Under Nyquist conditions, exemplified by baseband pulses having a square\u2010root raised cosine spectrum, this filter exhibits an impulse response satisfying the extended zero\u2010crossing property, that is, it vanishes for all integer multiples of the symbol period including the origin. Using this idea for symbol\u2010timing recovery, it is shown that the annoying jitter floor \u2013 typical for most timing recovery schemes and caused by inter\u2010symbol interference \u2013 can be avoided irrespective of the selected modulation scheme.
