ABSTRACT:
A method and apparatus for mitigating error in a received communications signal includes an error mitigation unit (245) which receives and performs mitigation based on an error indication (e.g., a CRC) and a quality indication (QI). The error mitigation unit may include a magnitude adjuster (220) for adjusting the input signal value (e.g., an ADPCM nibble) when the QI is less than a threshold, and a soft correction unit (240) for, when the QI is above the threshold, either soft correcting nibble magnitudes or muting selective nibbles based on further signal information such as differential phase.
