Abstract
Method and apparatus for signal detection in dynamic channels with high carrier frequency offset are provided. A coherent detector and a non-coherent detector are operated in parallel on a block of samples of an input signal to determine respective time offset candidates of the input signal. The time offset candidate obtained from the non-coherent detector is used to determine a frequency offset candidate of the input signal.
