ABSTRACT:
A method of determining an encoding rate associated with a received data frame in a communication system includes decoding (101) the received data frame at a first and second encoding rates to determine a first and second total metric, calculating (102) a discriminant function based on the first and second total metric, comparing (103) the discriminant function to a range of predetermined values having an upper predetermined range limit and a lower predetermined range limit, and selecting (104) one of the first and second rates as a determined encoding rate based on comparing (103) depending on whether the discriminant function is above the upper predetermined range limit or below the lower predetermined range limit.
