Abstract

The invention discloses a low-complexity polarization parameter estimation and tracking device and method. The device comprises an antenna signal processing module and a polarization parameter estimation module; the antenna signal processing module comprises multiple subarray signal processing modules, analog signal beams received by a mixed dual-polarized antenna array is formed and converted into a digital signal; and the polarization parameter estimation module is used for performing signal processing on the output of the antenna signal processing module to estimate an incoming wave polarization parameter. The signal is received by adopting a plane mixed dual-polarized antenna array, the self-adaptive tracking and estimation of the incoming wave angle of arrival can be sufficiently utilized to improve the beam forming receiving signal-to-noise ratio, thereby improving the estimation precision and convergence speed of the parameter estimation, and the calculation process only relatesto ordinary four arithmetic operation, the calculated quantity is small, and the realize is fast.

Description

technical field

[0001] The invention belongs to the technical field of signal processing, and relates to a low-complexity polarization parameter estimation and tracking device and method. Background technique

[0002] Hybrid antenna array, as a new adaptive antenna structure supporting future millimeter-wave high-speed communication, has attracted extensive attention in the field of array signal processing due to its potential advantages in balancing hardware cost and performance, array gain, and transceiver size. It consists of multiple analog sub-arrays, each containing a digital processing link. On the one hand, the use of analog subarrays can effectively generate antenna gain and alleviate the space limitation problem of the RF link. On the other hand, multiple digital links can provide multiplexing capability, high flexibility, adaptability and performance optimization.

[0003] The traditional single-polarization antenna can only receive the single-directional electr...
