Abstract: A method and apparatus for mitigating error in a received communications signal includes an error mitigator (35) of a communication unit (12) which receives and performs mitigation based on an error indication. In a first embodiment the error indication is a phase or non-used data symbol indicating error in ADPCM data, and mitigation includes changing certain nibble values to different predetermined values. In a second embodiment the error indication may include other parameters, e.g., a CRC frame error indicator, and an error estimator (34) determines a level of corruption in the ADPCM data. The error mitigator (35) applies a predetermined set of replacement values based on the indicated level of corruption and the mitigated data is subsequently decoded in an ADPCM decoder (26).
