A new method to count the expected value and variance of time dispersion is presented for time dispersion of underwater optical wireless communication. Instead of the typically used Gamma distribution, inverse-Gaussian distribution is suggested for underwater optical impulse response time waveform function. The expectation of this method is in good agreement with experimental data. Future works may include water absorption to the model.
