Can hamming code detect burst errors
By upper bound, we mean a limit on our error detection ability that we can never go beyond. Suppose that we want to design an code that can detect all burst errors of length A natural question to ask is: given and , what is the maximum that we can never achieve beyond? In other words, what is the upper bound on the length of bursts that we can detect using any code? The following theorem provides an answer to this question. WebShow how Hamming code cannot correct these errors. the 3rd and 7th bits are M1 and M4 C1 + M1 + M2 + M4 + M5 + M7 = 0 C2 + M1 + M3 + M4 + M6 + M7 = 0 C3 + M2+M3+M4+M8 = 1 ... If you want to detect burst errors of length less than or equal to r, the degree of your generator polynomial must be r If r is less than (i-j) where i and j are …
