Abstract:
A method of determining a value of a bit received in a transmission in a radio communication system, said bit being repeated at least once In said transmission, said method comprising the steps of:associating with the received bit and each received repetition of the received bit, a reliability value that is independent of the actual value of the received bit and of the other received repetitions of the bit, said reliability value indicating on a numerical scale, a reliability weighting that is independently assigned to each bit and each bit repetition; adding together, for the bits and bit repetitions that have actual values equal to 0, the associated reliability weightings of those bits and bit repetitions, thereby yielding a first total reliability weighting; adding together, for the bits and bit repetitions that have actual values equal to 1, the associated reliability weightings of those bits and bit repetitions, thereby yielding a second total reliability weighting; performing a comparison of the first total reliability weighting and the second total reliability weighting; deciding that said actual value of said bit is equal to 0 if the first total reliability weighting is greater than the second total reliability weighting; and deciding that said actual value of said bit is equal to 1 if the first total reliability weighting is less than the second total reliability weighting.
