Query: Performance Analysis of SPAD-based OFDM   In this paper, an analytical approach for the nonlinear distorted bit error
rate performance of optical orthogonal frequency division multiplexing (O-OFDM)
with single photon avalanche diode (SPAD) receivers is presented. Major
distortion effects of passive quenching (PQ) and active quenching (AQ) SPAD
receivers are analysed in this study. The performance analysis of DC-biased
O-OFDM and asymmetrically clipped O-OFDM with PQ and AQ SPAD are derived. The
comparison results show the maximum optical irradiance caused by the nonlinear
distortion, which limits the transmission power and bit rate. The theoretical
maximum bit rate of SPAD-based OFDM is found which is up to 1~Gbits/s. This
approach supplies a closed-form analytical solution for designing an optimal
SPAD-based system.
