Abstract
With the continuous development of power line communication technology, traditional single antenna systems are no longer able to meet the needs of modern power networks. Therefore, power line communication systems based on MIMO technology have begun to receive widespread attention and application. This article will first introduce the basic concepts, principles, and characteristics of MIMO technology, as well as the application of multi-antenna systems in power line communication. Secondly, for the MIMO based power line communication system, the overall fr amework, key technical points (channel estimation, modulation method, signal processing algorithm, etc.), design principles, and interface standards of the system were analyzed. Finally, based on actual power line communication application scenarios, the performance advantages and disadvantages of MIMO based power line communication systems were explored. Specifically, its performance advantages and disadvantages were analyzed in order to provide some reference for the design and implementation of power line communication systems.
