Repetition code is an (r,1) coding scheme that repeats the bits across a channel to achieve error free communication (r is the number of bits in each codeword for each data bit to be coded). Repetition code is generally a very naive method of encoding data across a channel, and it is not preferred for Additive White Gaussian Noise Channels (AWGN), due to its worse-than-the-present error performance. Repetition codes generally offer a poor compromise between data rate and bit error rate, and other forms of error correcting codes can provide superior performance in these areas. The chief attraction of the repetition code is the ease of implementation.
