ABSTRACT:
A bit error position is estimated. The estimation method includes generating data indicative of a substantial number of bit error locations in data frames. The generation of the data includes re-encoding decoded bit stream, mapping the bit stream to a first set of symbols, and determining a soft decision distance between a second set of symbols received through a data transmission channel and the first set of symbols. The generated data is then used to estimate the bit error locations. The estimation process includes capturing metric data for each bit in the data frame and obtaining derivative of the metric data. The derivative may be filtered for further processing. Error position estimation criteria may then be applied to estimate the bit error positions.
