Patent ID: 7830970

Claim:
A receiver for a multi-carrier communication system, the receiver being arranged for receiving training pilot carriers (TRPC) during a training symbol (T 1 , T 2 ) preceding data symbols (DS) comprising data carriers (DC) and data pilot carriers (PC), the receiver comprising: a correction unit ( 171 ) for supplying, under control of a control signal (CEC), a corrected signal (CDC 1 ) comprising information on the data carriers (DC) being corrected for a common amplitude error and/or common phase error, a quality determination unit ( 174 ) for determining which ones of the training pilot carriers (TRPC) occurring at positions of the data pilot carriers (PC) fulfill a predetermined quality criterion, and a control unit ( 175 ) for supplying the control signal (CEC) being dependent on an amplitude and/or phase of the data pilot carriers (PC) of which corresponding training pilot carriers (TRPC) fulfill the predetermined quality criterion, and not on the data pilot carriers (PC) of which corresponding training pilot carriers (TRPC) do not fulfill the predetermined quality criterion, wherein the control unit ( 175 ) is arranged for averaging the amplitude and/or phase of the data pilot carriers (PC) of which the corresponding training pilot carriers (TRPC) fulfill the predetermined quality criterion to provide an estimate for the common amplitude error and/or common phase error.
