Abstract
A method in a QAM receiver () for performing timing recovery. The QAM receiver () is configured to receive a sequence of symbols. Each symbol is represented by a respective IQ pair comprising a respective inphase component I and a respective quadrature component Q. The QAM receiver () samples the respective I component and the respective Q component with a relative timing offset between the sampling of the respective I component and the respective Q component. The QAM receiver () establishes a first value associated to a quality of the I component samples, and a second value associated to a quality of the Q component samples, and compares the first value and second value to determine if the sampling timing should be advanced or delayed to improve the sample quality. The QAM receiver () adjusts subsequent sampling by advancing or delaying a sampling timing based on the comparison.
