Methods and systems are provided for using error related feedback during signal processing. During handling of an input signal, each of a plurality of sub-carriers in the input signal is processed, and error-related information for each one of the plurality of sub-carriers is determined based on the processing. Aggregate error-related information is generated based on error-related information of each of one of the plurality of sub-carriers, and subsequent processing of at least one of the sub-carriers is adjusted based on the aggregate error-related information. The error-related information may comprise phase error-related information. Adjustments to subsequent processing of one or more of the sub-carriers may be determined based on processing-related information corresponding to different stages during processing of each of the plurality of sub-carriers.
