ASK QAM FSK signal generating function
no vote
Application background Application in communication signal to generate the basic function, mainly expounds the ask, FSK and QAM modulation generating function, to achieve 8qam, 16QAM and 64QAM modulation signals in time domain, widely used in the communication system of the policy and analysis. Key Technology FSK ask QAM signal communication function, can through the input frequency, code width, pulse width and other parameters, carries on the control to the control signal is generated, the needs of communication signals.

SystemView modulation and demodulation of 16QAM so
4.5
Application background Application in communication system signal modulation and demodulation for example, through the Systemview software to build simulation platform for communication system and gives the signal modulation and demodulation process and waveform specific forms, and the actual communication environment, communication channel simulation by Gaussian noise. Key Technology SystemView is mainly used to build a communication system platform, the use of the software in the relevant parts of the signal modulation and transmission. The low pass filter to obtain baseband signal, then the SPDT Switch device to complete the sentence, decoding.
