Simulation Design of Error Control System Based on Convolutional Code

Abstract

This paper completes the design of control system simulation of convolutional code error based on MATLAB software platform, the convolution encoding the input signal through the AWGN channel transmission, the receiver decodes the statistical transmission error rate, different rate and different SNR BER statistics under the receiver. The practice shows that the smaller the bit rate, the smaller the interference and the smaller bit error rate, and the higher the signal-to-noise ratio, the smaller the bit error rate.
