SYNCHRONIZATION METHOD AND RECEIVER COMPRISING MULTIPLICATION MEANS, TRANSFORM AND COMPARISON MEANS

摘要

The invention relates to a synchronization method and a receiver used in a radio system in which synchronization is made to a received signal, the radio system comprising at least one receiver (100, 200, 300) which receives modulated and partly previously known signal consisting of symbols and which signal contains time and frequency deviation. The receiver comprises multiplication means (402) for multiplying the received signal by the known part of the received signal for obtaining a product, transform means (403) for correlating the product in order to obtain a ratio and comparison means (404) for comparing the ratio with a pre-set correlation threshold value, on the basis of which comparison a decision is made on synchronization to the received signal.
