IntroductionIn this lab, I know the principle of DSB/SSB modulation and demodulation and Hilbert transform. And I draw the LabVIEW program diagram for DSB/SSB modulation and demodulation. By observi...

Introduction:In this lab, I have learnt the basic concepts and steps of AM. At the same time, I understand deeply the difference between envelope detection and coherent detection by construct the La...

Introduction: In this lab, I review the knowledge about the principle of narrow band frequency modulation and wide band frequency modulation. Then I used the LabVIEW to simulate the process an...

Introduction I design two program diagrams to two exercises to verify the principle of sampling and quantization. In the simulation experiment of sampling, I use convolution operator to com...

Introduction In this lab, I learnt the knowledge about eye pattern, inter-symbol interference and raised-cosine function. I also tried to derive the formula of raised-cosine function to exp...

Introduction In this lab, I learnt the principle of Phase Shift Keying (include Quadrature Phase Shift Keying and Binary Phase Shift Keying). Then I design a LabVIEW program to simulate th...

Introduction In this lab, we aim at analyzing the BER for PSK in AWGN channel on LabVIEW. And achieve two kinds of basic QAM which are 16 QAM and 64 QAM. After that, we recorded the BER of eac...
