Abstract
A method and apparatus for processing demodulated data comprising received symbol data is disclosed. A decoder is used to compute estimated symbols and corresponding reliability metrics. The reliability metrics are transformed into reliability weights. Optionally, residuals relating to the difference between the received symbol data and the estimated symbols are computed. Output data are generated comprising any combination of the following: estimated symbols, reliability weights, residuals, and received symbol data. The residuals may be weighted by the reliability metrics and used by demodulation or error compensation loops to instantaneously reduce or increase the bandwidth of these loops.
