How to design a block interleaver for Reed Solomon Coding
|28 Oct 2010||Mathuranathan Viswanathan||
Suppose, assume that the dominant error mechanism in a channel is of burst type. A burst of length b is defined as a string of b unreliable consecutive symbols. If the expected burst length, b is less than or equal to t (the number of correctable symbol errors by RS coding), the code can be used as it is. However, if bursts length b >t, the error correcting code will fail. This is where interleaving comes to our rescue.
