description The invention discloses a method for calculating the bit error rate (BER) of an underwater wireless optical communication system based on parallel multi-hop architecture. The method comprises the following steps: establishing a transmission model suitable for a parallel multi-hop-underwater wireless optical communication system by adopting an optimal path selection scheme of a maximum and minimumcriterion based on LN ocean turbulence distribution under the consideration of the effect of path loss; deriving a system probability density function and a cumulative distribution function under thejoint action of LN turbulence and the path loss; obtaining a closed system BER expression with a Gauss Laguerre polynomial, and performing simulation verification by a Monte Carlo method; bringing different parameters into a closed average BER expression to obtain the influences of the parameters on system performance; and introducing LDPC coding to compare the influences of different structure parameters, bit rate and max
