Turbo codes offer better performance when compared to convolutional codes at moderate BER (Bit Error Rate) and large block length. It works on the principle of efficient iterative decoding method. Turbo-codes were introduced to decrease the complexity of iterative turbo decoding while the performance of the system is close to Shannon capacity. Repeat Accumulate, irregular repeat accumulate and accumulate repeat accumulate codes are some of the recently invented turbo-like code. Turbo codes are used in many important wireless protocols from deep-space communications to mobile communications.
