A simulation method for a cascade communication system comprising a nodes sequence numbered as 1 to N from a transmitter to a receiver, comprises: acquiring simulation parameters; calculating reverse transfer functions of the nodes; determining a current node in the sequence; adding noise that should be added at the current node to a simulation signal of a previous node; simulating the current node to generate a simulation signal of the current node, by using the simulation signal of the previous node added with the noise that should be added at the current node, based on the reverse transfer function of the current node; judging whether simulations of all the nodes are completed; if yes, repeating the adding and the simulating; if not, determining a cost of the based on the simulation signal of the current node. |
