In cyclic codes and other linear block codes used in digital communications, binary addition does not follow the normal carry-based binary arithmetic. Instead, it uses modulo-2 addition , also known as the bitwise XOR operation . This method is simple, fast, and widely used in error-detecting and error-correcting algorithms. Understanding Modulo-2 (XOR) Addition Modulo-2 addition works bit by bit, and it does not generate carries. This means each bit is added independently, using the rules: 0 ⊕ 0 = 0 0 ⊕ 1 = 1 1 ⊕ 0 = 1 1 ⊕ 1 = 0 In short, XOR outputs 1 only when the bits are different. Example: 0101 + 1111 Let’s add the two binary numbers using modulo-2 addition: 0101 ⊕ 1111 ------- 1010 Step-by-Step Table Bit Pair Operation Result 0 ⊕ 1 0 + 1 (mod 2) 1 1 ⊕ 1 1 + 1 (mod 2) 0 0 ⊕ 0 0 + 0 (mod 2) 0 1 ⊕ 0 ...
