Abstract

Indoors wireless infrared transmission is severely impaired by ambient noise. In addition, in a multiple user network, since many users share the same physical channel, considerable amount of multi-user interference will also be introduced. Infrared CDMA techniques are proposed to combat the effect of ambient and multi-user interference. Our analysis is based on photon counting approach and the bit error rate is given versus signal power. The results show that using infrared CDMA techniques, transmission can be performed well below the ambient noise power with transmission power that satisfies eye-safety power regulations
