2PSK-based wireless carrier communication system
Abstract:First of all, the system from analog signals, digital communication systems as a result of the source code to be part of the analog inputof digital signals, the first study of its conversion into a digital signal.Followed by analysis of the digital signal modulation and demodulation, the main method of modulation is binary phase shift keying (2FSK), the receiving end of the demodulator is the inverse of the modulation process. And then use the SystemView software to system simulation.
With the digital baseband signal control carrier, the digital baseband signal transform for the digital communication, with the process called digital modulation. Key control method, such as the carrier the phase of keying, can binary phase shift keying (2PSK) basic modulation mode. 2PSK in life because of a wide range of applications, this paper introduced the waveform and the formation of the PSK simulation process. We can understand the basic principle of the system, and get the digital modulation wave method. Use of systemview simulation can better understand 2PSK signal waveform modulation of the process.
