Linear unequal error protection codes
I. M. Boyarinov, G. Katsman · IEEE Transactions on Information Theory · 1981
The properties of linear codes over GF(q)that provide unequal error protection (UEP) of information digits are discussed. A design is proposed for optimal binary systematic linear UEP codes. Broad classes of iterative and concatenated UEP codes are constructed. Majority decoding algorithms for linear iterative UEP codes are described.
