Digital Modulations using Matlab is a learner-friendly, practical & example driven book for solid background to build simulation models.
If you want to separate the in-phase and quadrature components of the complex modulated signal, you can use theComplex to Real-Imag(Simulink)block, or therealandimagMATLAB®functions. As appropriate for a given modulation method, you can visualize the complex modulated signal by viewing the: ...
For the analysis, modulation signals and their spectrograms were obtained in the Matlab program. The classification method is based on spectrogram image recognition and it can discriminate between various digital signal modulations, such as FSK, BPSK, MSK, QPSK and QAM. The new method was tested ...
system design6,7. Widening the bandwidth beyond these bounds is possible only by breaking one or more of the underlying assumptions on time invariance, passivity, and linearity3,4. Temporal modulations of antenna elements or the connected matching circuitry have been proven to be effective in this...
For practicality, we would love to adapt the best and choosen architecture for researchers who are in the area of communications, by writting it in MATLAB using 'Deep learning toolbox'. But unfortunately, this toolbox is no longer maintained and updated, we will investigate this, and try to...
V.32/V.22/V22bis Soft Modem Library by VOCAL Technologies, LTD The Soft Modem Library is a collection of data modulations and protocols (V.32, V.22, V.22bis, V.23, V.21, Bell 103, Bell 212A and Bell 202). This library is provided with archives that contain object code modules,...
github/ci: bumping checkout action, using brew to install autoconf deps 8个月前 autotest autotest: including internal header instead of directly 7个月前 bench benchmark: recording number of attempts to reach target runtime 1年前 examples ...
The stimuli were defined by disparity modulations of fields of spatially bandpass dots. They were generated from an isotropic log-Gabor function with a spatial frequency of 0.5c/deg and a bandwidth of 2.4 octaves. They have the appearance of a central light blob with a darkened surround. Presen...
