提出了一种新颖的金字塔形蝇眼分集结构，用于中小型办公室的无线通信。结果表明，在半分散环境下，该结构能有效地抑制多径色散，提高接收功率。由于配置中光电探测器的数量是有限的，因此性能提高的代价是复杂性的有限增加。根据石膏墙的反射特性，提出了一种新的计算方法，可以准确地计算各种检测到的脉冲响应。脉冲响应在测试室内的不同位置显示，既为单个光电探测器和锥体蝇眼接收器。
A novel, pyramidal fly-eye diversity configuration is presented for wireless communication in small and middle-sized office rooms. It is demonstrated that the configuration combats multipath dispersion and increases the received power level in a semi-disperse environment. Since the number of photodetectors in the configuration is limited, the penalty paid for an increase in performance is a limited increase in complexity. A new computation method, based on the reflection properties of plaster walls, is derived for an accurate calculation of the diverse detected pulse response. Pulse responses at various locations within a test room are displayed, both for a single photodetector and the pyramidal fly-eye receiver.
