BER Performance of NRZ-OOK and Manchester Modulation in Indoor Wireless Infrared Links
International Journal of Wireless Information Networks, 1998 This paper describes a novel approach to theevaluation of the bit error rate (BER) performance ofoptical wireless links that takes into account shotnoise, fluorescent light interference, and intersymbol interference (ISI) from both multipathdispersion and high-pass filtering (HPF) at thereceiver. The calculation of the BER is achieved withthe use of an
