If you are curious, it is for a Softrock RXTX ham radio transceiver that provides I and Q signals at 192 kHz. Unfortunately, some of Matlab's DSP routines require me to convert back to a real signal for further processing (e.g. dsp.DigitalDownConverter). The IQ signal from the radio is centered at DC and has a true bandwidth of Fs = 192 kHz..
The R&S I/Q File Converter is a simple tool to convert the Rohde&Schwarz specific I/Q file formats “*.wv”, “*.iqw” and “*.iq.tar” among each other. Besides that, it is also possible to convert I/Q files to “*.mat”-files that can easily be imported to Mathworks Matlab or to human readable ASCII files... Feb 10, 2015 · It multiplies two voltages: the RF signal that you want to down-convert and a sine signal coming from a local oscillator (LO). The output is usually nicknamed “intermediate frequency” (IF). The magic lies behind a simple trigonometric formula. The product of two sine signals of frequencies F1 and F2 is the sum of two other sine signals..

The IQ signal from the radio is centered at DC and has a true bandwidth of Fs = 192 kHz. "/>. $\begingroup$ @2one: I can't say much more than I did in my previous comment. You have to know the bandwidth of your IQ data, you have to know the sampling rate of the IQ data, and the frequency of the carrier. You choose the new sampling frequency according to the formula in my previous comment. E.g., if the RF sampling frequency is 20MHz and the IQ sampling frequency is 2 MHz, then the.
Below is my MATLAB code for QPSK commnication ]; % inphase signal vector y_qd=[y_qd y2]; %quadrature signal vector y=[y y1+y2]; % modulated signal vector end Tx_sig=y; % transmitting signal after modulation tt=T/99:T/99:(T*length(data))/2; figure(2) subplot(3,1,1); plot(tt,y_in,'linewidth'.
Filters remove unwanted signals and noise from a desired signal . There are many different kinds of filters, including low pass, high pass, band pass In the following example, the filter function is used to remove high frequency interference from a lower frequency signal ..
Convert Complex data to Real. Hello, If I have a complex signal with sample rate @10MSps, is there any way to convert it to a real signal with twice the amount of points @20MSps. From a graphical point of view, using an FFT, if we construct a double sided spectrum from the complex data we can see from -5MHz to +5MHz (since it is constructed. Description. scatterplot (x) creates a scatter plot to display the input signal x in the IQ-plane. Specifically, the IQ-plane displays the in-phase and quadrature components of a modulated signal on the real and imaginary axis of an xy-plot. scatterplot (x,n) specifies decimation factor n. The function plots every n th value of x, starting from ....
It should be possible to export both the depth map and the IR data to MATLAB by saving the frames in an array, which can be afterwards used for further processing. The depth map which comes from the camera is already compensated to take into account the camera's intrinsic values, so it can be used directly to display the point cloud.
