A synchronization method and a receiver used in a radio system in which synchronization is made to a received signal are provided. The radio system includes at least one receiver, which receives a modulated and partly previously known signal that includes symbols. The received signal also contains a time and frequency deviation. The receiver includes a multiplier, a transformer and a comparator. The multiplier multiplies the received signal by the known part of the received signal in order to obtain a product. The transformer correlates the product in order to obtain a ratio. The comparator compares the ratio with a pre-set correlation threshold value. Based upon the comparison made by the comparator, a decision is made whether the received signal is synchronized.
