类 ReedSolomonDecoder

java.lang.Object

com.google.zxing.common.reedsolomon.ReedSolomonDecoder

public final class ReedSolomonDecoder
extends java.lang.Object

Implements Reed-Solomon decoding, as the name implies.

The algorithm will not be explained here, but the following references were helpful in creating this implementation:

• Bruce Maggs. "Decoding Reed-Solomon Codes" (see discussion of Forney's Formula)
• J.I. Hall. "Chapter 5. Generalized Reed-Solomon Codes" (see discussion of Euclidean algorithm)

Much credit is due to William Rucklidge since portions of this code are an indirect port of his C++ Reed-Solomon implementation.

decode

public void decode(int[] received,
                   int twoS)
            throws ReedSolomonException

Decodes given set of received codewords, which include both data and error-correction codewords. Really, this means it uses Reed-Solomon to detect and correct errors, in-place, in the input.

参数:

received - data and error-correction codewords

twoS - number of error-correction codewords available

抛出:

ReedSolomonException - if decoding fails for any reason
