摘要
The present invention provides a cycle-slip detection method and apparatus, and a receiver. If an absolute value of a first difference obtained by subtracting a phase of a first symbol in a kth training sequence cycle from a phase of a last symbol in a (k−1)th training sequence cycle in a received signal is greater than a cycle-slip determining threshold, it is determined that a cycle-slip occurs in the kth or (k−1)th training sequence cycle. Further, if a second difference obtained by subtracting a phase of the first symbol in the (k+1)th training sequence cycle from a phase of the last symbol in the kth training sequence cycle is greater than the cycle-slip determining threshold, and signs of the first difference and the second difference are opposite, it is determined that a cycle-slip occurs in all symbols in the kth training cycle.
