By conducting simulation experiments on convolutional code encoding and Viterbi decoding, we can compare and analyze their performance differences and advantages. In this experiment, we will thoroughly investigate the convolutional encoding process and Viterbi decoding algorithm, performing comprehensive performance evaluations. A typical implementation would involve generating convolutional codes using shift registers with specific polynomial generators, while the Viterbi decoder would employ trellis-based path metric calculations and traceback mechanisms. These simulations allow deep understanding of convolutional code and Viterbi decoding principles, providing crucial reference basis for future communication system design and optimization. The simulation code would typically include modules for channel modeling, error rate calculation, and performance visualization through BER vs SNR plots.
