Abstract :
This paper presents the first results of a study developed to evaluate the performance of sectored receivers in combating the multipath dispersion of the indoor optical channel. We intend to: (1) evaluate the performance of sectored receivers in minimizing multipath dispersion and, (2) conclude if sectored receivers may be used successfully to reduce both ambient noise and multipath dispersion, by estimating only the ambient noise at each sector of the receiver. The results show that sectored receivers can reduce significantly the multipath dispersion, but selection of the sector with the best impulse response is required. Also, to achieve significant gains the field-of-view of the sectors have to be smaller than 50°
