Abstract
In this paper the Viterbi decoder which is used for TCM decoding in wireless modem system under transmission of audio data for the high quality sound is designed by VHDL and implemented by FPGA. After making short explanation about TCM encoding and decoding. I show the effect of channel in computer by using encoder and decoder implemented in FOGA and the bit error rate according to change rate of ($E_b/N_0$).
