A receiver, system and method for providing symbol timing recovery that allows for inexpensive and low-complexity synchronization for communication systems. A receiver receives a signal including digital data in the form of packets that is transmitted from a transmitter. The receiver uses information contained in each of the packets to align a phase of the receiver clock with a phase of the transmitter clock. The receiver further controls a sampling device such that the in-phase (I) and quadrature (Q) components are sampled at an optimum sample rate and at an optimum instance of time without requiring a numerically controlled oscillator or voltage controlled oscillator.

Low complexity synchronization for wireless transmission

An apparatus and method for concealing errors in digital data. An interpolator estimates a value of a sample of digital data from other samples of the digital data. The interpolator has an input for inputting the digital data and an output for outputting the estimated value of the sample of the digital data. A holding unit has an input for selectively receiving the sample of the digital data only when the sample is error free, and an output for outputting the error free sample. The input of the holding unit may be in parallel with the input of the interpolator. A selector selects between outputting the estimated value of the sample of the received digital data from an output of the interpolator and outputting the error free sample of the received digital data from an output of a holding unit based on at least one error indicator.
