摘要
文章针对物联网通信中的Polar码研究了一种可变步长的编码方法,并探讨了固定码长与可变码长两种不同编码方法的性能比较.通过对比两种方法在不同信噪比条件下的误码率表现,结果显示可变码长Polar码在各个信噪比条件下均优于固定码长Polar码.这一研究为极化码在通信系统中的应用提供了重要参考,对于提高通信系统的可靠性和性能具有一定的指导意义.
Abstract
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.
