Given a received polynomial rx with coefficients in finite field soft decision decoding SDD is the process of identifying the most probable error polynomial ex with coefficients in finite field and hence the corresponding code polynomial cx ∈{C x}, where {C x} is the code set. The paper presents an algorithm for identifying this cx - called the target code word TCW here - and extends the same to identify the list of codewords as well. The uniqueness of the approach lies in identifying the TCW directly without the need for search over a much larger set as with many of the existing methods. The proposed method seeks codewords with the most likely error positions guessed in advance; this ushers in a further simplification with cyclic codes obviating the need for repeated algebraic decoding. The fact that restricting the error correcting range to dmin - 1 yields a unique decoded codeword, leads to a practical implementation of the said algorithm with attendant superiority in performance.
