—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)
— 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)
