摘要

给出了不同路径下的分集改进结果。传播试验在陆地和水上的路径上进行。使用了几种天线波束配置来澄清通过使用倾斜波束、波束宽度和空间分集接收获得的接收功率的改进。为了评估多样性的改善，推导了一个三射线模型。结果表明，多样性的改善明显依赖于路径条件。因此，为了达到最佳的分集改进，需要考虑路径条件

Tilted-beam, beam-width- and space-diversity improvements on various paths

Results of diversity improvements on various paths are presented. Propagation tests were conducted on paths over land and water. Several antenna beam configurations were used to clarify improvements in received power obtained by using tilted-beam-, beam-width-, and space-diversity reception. In order to evaluate the diversity improvement, a three-ray model is derived. The results show that diversity improvement is clearly dependent on the path conditions. Thus, path conditions should be considered in order to achieve the best diversity improvement.<>
