So, on addingįor example, suppose we have given 3 codewords (110, 101, 011). Suppose we have two codewords C i and C j. Let us now understand on following which properties a code is said to be of cyclic nature.Īccording to this property, a linear combination of two codewords must be another codeword. We have mentioned at the beginning itself that cyclic codes fall under the category of linear block codes. While the other i.e., a binary adder has two inputs and one output. The fundamental elements of shift registers are flip flops (that acts as a storage unit) and input-output. Using a shift register, encoding can be efficiently performed. can be represented using cyclic codes.īasically, a shift register and a modulo-2 adder are the two crucial elements considered as building blocks of cyclic encoding. Various other important codes like, Reed Solomon, Golay, Hamming, BCH, etc. These are used in error correction as they can check for double or burst errors. Cyclic codes are known to be a crucial subcategory of linear coding technique because these offers efficient encoding and decoding schemes using a shift register.
