The Channel Impulse Response of SIMO Underwater Optical Wireless Communication Link based on Monte Carlo Simulation

In underwater optical wireless communications (UOWC)the channel impulse response is essential in characterizing the link. In this paper we investigate the impulse response of the single input multiple output UOWC link using Monte Carlo simulation for different types of waters. We simulate the bit error rate (BER)performance for the proposed intensity modulation direct detection SIMO UOWC links for multiple receivers with a linear combining scheme by considering absorption, scattering, turbulence and all major noise sources. We show that, the clear, coastal and harbor waters display the best to the worth BER performance, respectively.
