Numerical Simulation of joint processes in Ocean Waves

Based on the methods of simulating single process in ocean waves proposed by Borgman,Goda,etc.,three simulation techniques for joint processes are presented.The first one is characterized by regression of the processes to be simulated;the second,as discussed by Borgman in his paper,is associated with the multiple linear system selected properly,with the vectorvalued white noise processes as its inputs the third is based on the superposition of an infinite number of component waves.These approaches can be considered as generalization of those methods for single process in ocean waves used before.In addition,design of numerical filters is described.
