Digital pulse-position modulation (PPM) is attractive to apply in wireless optical-telemetry systems because of its power efficiency. Usually, the bit-error rate is assumed to depend solely on the noise level. The detrimental influence of optical interference is overlooked. In this paper, interference measurements are reported, models that describe(More)
Digital pulse position modulation is an attractive modulation scheme in indoor wireless optical transmission systems because of its power efficiency. In this brief, slot synchronization by means of a reduced pulsewidth is discussed, the scheme is compared to on–off keying, and design rules for slot synchronizers are presented. The sensitivity deterioration(More)
