Abstract :
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
