Methods and associated structures for improved erasure correction and detection in digital communication channels utilizing modified Reed-Solomon decoding of encoded digital data. Methods and associated apparatus in accordance with features and aspects hereof perform Galois Field element generation in descending order for Reed-Solomon erasure detection and correction. Real time computation of Galois Field elements in descending order as required for erasure detection and correction features and aspects hereof eliminates the need for costly, complex, large, high speed lookup tables as previously practiced in the art for storing Galois Field element values pre-computed in the same ascending order of reception of the encoded code words. Features and aspects hereof may thus be applied in digital read channel applications including, for example, digital telecommunications receive/read channels and digital data storage read channels.
