Abstract
An error rate sensitive error correction (ERSEC) system that applies a level of error correction that is inversely related to susceptibility to error as indicated by a signal-to-noise ratio (SNR) profile of a channel. The SNR profile is estimated, detected or retrieved from an external source. The ERSEC system can be used with any channel for which the SNRs vary spatially, temporally or both.
