A pre-verifying method for software/hardware design of a communication system includes simulating a process of sending a data frame from a transmitter to a receiver with a transceiver algorithm meeting a preset specification for obtaining simulation parameters. A transmitter hardware platform sends the data frame via an antenna. A receiver hardware platform receives an echo signal of the data frame and compares each parameter of the echo signal with the simulation parameters. The comparison result of various parameters of the echo signal and the simulation parameters is verified to be in a desired range or not. When the comparison result is not in the desired range, the transceiver algorithm is adjusted. When the comparison result is in the desired range, the transceiver algorithm is converted to a hardware program language format to be written in a programmable module to perform the action of the transmitter and the receiver.
