COMMENTS ON "WEIGHT DISTRIBUTION OF SOME WEIGHTED SUM CODES FOR ERASURE CORRECTION"
In , a new family of error detection codes called Weighted Sum Codes was proposed. In  it was noted that these
codes are equivalent to lengthened Reed Solomon Codes or to a shortened version of lengthened Reed Solomon Codes over
GF(2h/2). It was also shown that it is possible to use these codes for error correction of one error in the
codeword over GF(2h/2). In , a weight spectra of Generalized Weighted Sum Codes (GWSC-II) constructed over
GF(8) were presented. In the present paper, some possibilities to improve erasure correction capabilities of
these codes were investigated. At the end a brief analysis of erasure detection failure is given.
