Abstract
The invention concerns a method and a receiver configured to receive a radio signal carrying information, the radio signal including an overall frequency band having at least three different sub carriers. The receiver is further configured to receive, during a first time period, a first multitone signal carrying a first portion of the radio signal, the first multitone signal including a first and a second sub carrier which are received simultaneously, and to determine a first phase difference between the first and the second sub carrier. The receiver is further configured to receive, during a second time period, a second multitone signal carrying a second portion of the radio signal, the second multitone signal including the second and a third sub carrier which are received simultaneously, and to determine a second phase difference between the second and the third sub carrier. According to the invention, the receiver is configured to determine a phase difference between the first and the third sub carrier using the first phase difference and the second phase difference.
