Abstract 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 efficient numerical technique based onnonclassical Gauss Quadrature Rules. Fluorescent lightinterference is modeled as a Fourier series expansionwith coefficients taken from measurements, whilemultipath-induced ISI is calculated by using previouslyreported IR channel models. Application of the techniquepresented here allows for the calculation of the optimumHPF cutoff frequency that minimizes the overallperformance penalty. Finally, as an application of this method, the BER performance of NRZ-OOK andManchester (2-PPM) modulation is evaluated and numericalresults are presented for different linkscenarios.
