Viterbi decoder
A decoding algorithm developed in the late 1960s by Andrew Viterbi that is used to decode a particular convolutional code. Viterbi decoders have been the most effective way to decode wireless voice communications in satellite and cellphone transmissions. Viterbi outputs a 0 or a 1 based on its estimate of the input bit. See CDMA, convolutional code and turbo codes. |

| In the CDMA technology, the Viterbi decoder in the cellphone is used to correct the errors in the convolutional code that was generated by the base station. See CDMA. |
