Method and apparatus for determining bits in a convolutionally decoded output bit stream to be marked for erasure
Abstract:
A method and apparatus are provided for determining bits in a convolutionally decoded output bit stream to be marked for erasure. K-bits and p-bits of the convolutionally encoded output bit stream may be compared with a corresponding k-bits and p-bits of a delayed version of the input bit stream. For each bit of the k-bits (p-bits) in the convolutionally encoded output bit stream and in the corresponding k-bits (p-bits) of the delayed version of the input bit stream, a number of or pattern of conflicting bits and whether the number of conflicting bits exceeds a threshold number or pattern of conflicting bits may be determined. The output bit stream may be sent to a block decoding component for decoding with the k-bit streams marked for erasure.
