With the development of technology, the functions of modern wireless communication system are becoming much stronger and the performance index of wireless are much higher. Complexity of communication system is increasing and the procedure description is very abstract. Corresponding to this, the cost of development is increase and the system of each part of the study become much more difficult. If the study of a wireless communication system to achieve with full practical equipment, ,not only costs of human、 material and financial resources are huge, but also increases the development cycle, besides some research facilities are not can effectively achieve. Therefore, analysis process plays an important part in design of communication system because of its economic simulation, flexible and lifelike features.
This first chapter described the importance of testing and simulation in communication system basically. The second chapter basically discussed the method to detect sinusoidal signal with AWGN noise, as ASK signals for example. This chapter also described how to calculate or set the best judgment threshold of receiver. The third chapter presented the method to detect and simulate signal using System View .The result of simulation is in accordance with the theory..
