WebDec 17, 2024 · Example 1: Hamming Distance Between Binary Vectors. The following code shows how to calculate the Hamming distance between two vectors that each contain only two possible values: #create vectors x <- c (0, 0, 1, 1, 1) y <- c (0, 1, 1, 1, 0) #find Hamming distance between vectors sum (x != y) [1] 2. The Hamming distance … In computer science and telecommunication, Hamming codes are a family of linear error-correcting codes. Hamming codes can detect one-bit and two-bit errors, or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error. Hamming codes are perfect codes, that is, they achiev…
