Research on Optimization of Polar Channel Encoding Technology in Internet of Things Communication
This paper studies a variable step coding method for Polar codes in Internet of Things communication,and explores the performance comparison of two different encoding methods:fixed code length and variable code length.By comparing the error rate performance of the two methods under different signal-to-noise ratio conditions,the results show that the variable code length Polar code is superior to the fixed code length Polar code under various signal-to-noise ratio conditions.This study provides important reference for the application of polarization codes in communication systems,and has certain guiding significance for improving the reliability and performance of communication systems.
