Forward Error Control (FEC) based on Convolution Encoders with Viterbi decoding is a good methodology to decrease the effect of Additive Gaussian Noise residing inside digital data transmissions channel. In this paper a Convolutional encoders with maximum free distance and different constraint lengths have been tested with AWGN channel effect using MATLAB. The performance and analysis has done by changing rates of Convolutional encoders and different constraint lengths and take in consider QPSK, 16-QAM and 64-QAM as modulation schemes.nbsp
