摘要：Data communication basically involves the transfer of data from one point to another. Error may beoccurred by the channel which makes the data unreliable for user and hence we have different error detection andcorrection schemes. This paper proposes the viterbi algorithm for error detection and correction by using trellismethod. In the data transmission, the error detection and correction with minimum latency and buffering is a majorproblem. This paper uses virtual channel to increase the throughput and efficiency of the system. It is the routerwhich is used to move message and reply on different channels and never have loop on a single channel. Deadlockcan be avoided during transmission. The viterbi algorithm uses feed forward control which means the error can beidentified before processing the data. In this paper, the viterbi algorithm having the capability of correcting up to 8 bitsand it doesn’t need any separate buffer for storing the error bits.Then we implement the design using Verilog, then simulated and synthesized using Modelsim SE 6.5 simulator andXilinx ISE 13.2i respectively.
