Decoding of convolutional codes using viterbi algorithm

The development of computer applications and widely emerged internet services enforces adaptation of more enhanced means for security. Information encryption is being demanded in order to prevent the autonomous attempts to claim the data. The challenges of information encryption are raised after the internet data inventory were invented as data broadcasting through a public network may be penetrated by unauthorized receivers. This paper is presenting the Viterbi algorithm that is manifested a robust solution for convolutional codes decoding. Two designs are being discussed namely convolutional coding with 1/2 and 5/3 code rates.
