Design and simulation of new type of digital band-pass modulators based on Systemview

To improve the performance of digital bandpass transmission systems, many improvements have been made to digital modulators and many new modulators have been proposed. Some of the hardware circuits of these systems can be realized using software which can save design time, shorten design period and raise the design efficiency. In this article, we design and simulate the quadrature amplitude shift keying and minimum shift keying in communication systems using Systemview software, the results are shown to be correct.
