Abstract:

Communication Engineering has been the important field of engineering in last few decades. Advancement of digital communication has made this field more interesting as well as challenging. Reliability and efficiency are the important goal of any communication system. In most cases reliability is given the priority over efficiency though at certain cases one is compromised for the other. Reliability of communication has an impact even in our day to day life. Communication has got many applications such as telephonic conversations etc. During the transfer of message, the data might get corrupted due to lots of disturbances in the communication channel. So it is necessary for the decoder tool to also have a function of correcting the error that might occur during transmission Convolutional encoding with Viterbi decoding has been in use for many years in commercial satellite systems. A characteristic of the Viterbi decoding process is that as the Eb/N0 (SNR) becomes increasingly smaller, the uncorrectable errors that are passed through the system are clumped together. Although the distribution of errors caused on the link is Gaussian, the uncorrectable error distribution looks like one found on a classical bursty channel. A class of codes that are well known to correct bursty errors is the Reed-Solomon code. The obvious conclusion is to use concatenate the Viterbi and Reed/Solomon codes.
