Abstract

The invention relates to an MIMO-Y type antenna array forming method based on electromagnetic vector sensors. The method includes the steps of firstly, calculating the incidence signal spatial guide vector when a plurality of antennas of a receiving end are in a Y type array; secondly, calculating the Y type array guide vector based on the electromagnetic vector sensors; thirdly, calculating the Y type array space fading relevancy function; fourthly, calculating the space fading relevancy when array elements of the Y type array are electromagnetic vector sensor units. By introducing the algorithm of the electromagnetic vector sensors (EVSs) into the Y type antenna array, system modeling for the MIMO is expanded, and the antenna design of an MIMO multi-antenna system terminal is optimized.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a MIMO-Y antenna array based on an electromagnetic vector sensor. Background technique [0002] In recent years, due to the rapid increase of mobile communication network users, the radio frequency spectrum has become increasingly crowded. In the past, we often increased system capacity by splitting cellular macrocells or microcells to alleviate congestion in cellular systems. However, the cost of splitting the cell is high and the cellular system needs to be reconfigured. Adaptive antennas can effectively solve this problem. The MIMO system composed of adaptive antennas can significantly increase the data transmission rate through multipath signal multiplexing, and can improve the receiving performance through diversity. Theoretically, the MIMO multi-path channel capacity can be doubled without occupying additional system spectrum resources. Therefore, the MIMO multi...
