A method for receiving, at a reception stage of a node of a radio communication network, a diversity-protected data flow divided in data units coded according to a forward error correction code, said method comprising: a) demodulating a first radio signal carrying said diversity-protected data flow thereby obtaining a first data flow and demodulating a second radio signal carrying said diversity-protected data flow thereby obtaining a second data flow; b) decoding a first data unit of said first data flow and a corresponding second data unit of said second data flow, generating first decoding information indicative of a result of said decoding said first data unit, and generating second decoding information indicative of a result of said decoding said second data unit, said first decoding information comprising a parameter indicating a number of errors comprised in said first data unit before decoding and said second decoding information comprising a further parameter indicating a number of errors comprised in said second data unit before decoding; and c) processing said first decoding information and said second decoding information and, based on a result of said processing, selecting one of said first data unit and said second data unit in order to obtain a retrieved data flow, characterized in that, at said step c), said processing comprises: - computing a first average of said parameter and previous parameters associated to previously received data units of said first data flow; and - computing a second average of said further parameter and previous further parameters associated to previously received data units of said second data flow. a) demodulating a first radio signal carrying said diversity-protected data flow thereby obtaining a first data flow and demodulating a second radio signal carrying said diversity-protected data flow thereby obtaining a second data flow; b) decoding a first data unit of said first data flow and a corresponding second data unit of said second data flow, generating first decoding information indicative of a result of said decoding said first data unit, and generating second decoding information indicative of a result of said decoding said second data unit, said first decoding information comprising a parameter indicating a number of errors comprised in said first data unit before decoding and said second decoding information comprising a further parameter indicating a number of errors comprised in said second data unit before decoding; and c) processing said first decoding information and said second decoding information and, based on a result of said processing, selecting one of said first data unit and said second data unit in order to obtain a retrieved data flow, characterized in that, at said step c), said processing comprises: - computing a first average of said parameter and previous parameters associated to previously received data units of said first data flow; and - computing a second average of said further parameter and previous further parameters associated to previously received data units of said second data flow. - computing a first average of said parameter and previous parameters associated to previously received data units of said first data flow; and - computing a second average of said further parameter and previous further parameters associated to previously received data units of said second data flow.
