Abstract
The invention concerns a method for receiving and a receiver configured to receive a radio signal (100) carrying information, the radio signal (100) comprising an overall frequency band (f overall ) having a first frequency sub band (101) and a second frequency sub band (102). According to the invention, the receiver is further configured to receive during a first time period (T 1 ) a first portion (111) of the information carried by the radio signal in the first frequency sub band (101), and to receive during a second time period (T 2 ) a second portion (112) of the information carried by the radio signal in the second frequency sub band (102). The receiver is further configured to perform a channel estimation (121) of the first frequency sub band (101) in order to determine a first phase (131) and to perform a channel estimation (122) of the second frequency sub band (102) in order to determine a second phase (132). According to the invention, the receiver is further configured to determine an overall phase basis (133) of the radio signal using the first and second phases (131, 132).
