Matlab code to generate QPSK waveform for the given binary sequence. Modulation is achieved by varying the phase of the basis functions depending on the message symbols. or can u give u ur personal email address plz so tht i would contact wid u if i feel some problem during doing the code. QPSK modulation is also performed on MATLAB tool, which gives three types of waveforms. The example uses some key algorithms in MATLAB, emphasizing textual algorithm expression over graphical algorithm expression. doc), PDF File (. The code of QPSK modulation and demodulation technique has been developed according to the theory. written in MATLAB. The top-level structure of the model is shown in the following figure. This object demodulates the input signal using the quadrature phase shift keying (QPSK) method. C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Connect two ADALM-PLUTO Radios to the computer. Graph is displayed in figure 3. Discover Live Editor. Thank you very much. Which includes a USRP receiver block, a QPSK Receiver subsystem and a BER Display blocks. The power of the spread QPSK data stream can be calculated using the following MATLAB command: Solution: The power of the spread QPSK data stream is calculated using the command in the line number 23 of the appended MATLAB code.
