摘要

本文提出了一种考虑到UHF频段内应用的阵列处理的原始传感器配置装置。主要目标是减少基于空间分集的经典多天线解决方案所需的体积。提出的解决方案将一组不同取向的并置单极子联系起来;在非平稳极化的多径传播假设下,它诱导了信道间相关性的显著降低。然后测试了低复杂度阵列处理,并与单通道解决方案相比提高了接收性能。

A Polarization Sensitive Array for DVB-H Applications
The paper presents an original device of collocated sensors designed for the implementation of array processing considering applications within the UHF band. The main objective is to reduce the volume required by a classical multi antennas solution based on space diversity. The proposed solution associates a group of collocated monopoles with different orientations ; it induces a significant reduction of the inter channel correlation under the assumption of a multi path propagation with non stationary polarizations. A low complexity array processing is then tested and improves the performances of the reception if compared to a single channel solution.
