Abstract
The utilization of the millimeter wave (mmWave) frequency band has accelerated the development of 5G wireless communication systems. Although mmWave offers abundant bandwidth resources and faster data rates, channel estimation and compensation techniques face significant challenges in high-mobility scenarios and complex urban environments. This paper focuses on the proposal and enhancement of channel estimation and compensation technologies within mmWave-based 5G systems. We have developed a novel channel estimation algorithm that integrates compressed sensing and machine learning techniques. This approach not only significantly improves the accuracy of channel estimation but also effectively reduces implementation complexity. Experimental results demonstrate that the proposed method delivers superior performance across various channel conditions, achieving approximately a 30% reduction in error rate compared to traditional methods.
