This MATLAB function corrects for a specified frequency offset, foffset, in the time-domain waveform, in, by performing simple frequency modulation (FM).
The paper begins with an introduction of applying high efficiency digital filter and math analysis in quadrature digital frequency modulation and demodulation to digital frequency conversion technique. Next, Simulink/Matlab is used to simulate digital telemetry receiver. The method of simulation, analysis ...
Use MATLAB to find and plot the poles and zeros and the corresponding magnitude and phase frequency responses of: (a) A second-order band-pass filter and a high-pass filter realized using a series connection of a resistor, an inductor, and a capacitor, each with unit resistance, inductance...
For more information on changing property values, seeSystem Design in MATLAB Using System Objects. Usage Syntax [outsig,phEst] = carrSynch(csync,insig) Description [outsig,phEst] = carrSynch(csync,insig)estimates the carrier phase offset of the input signal and returns the corrected signal in ...
Continuous wave modulation can change the amplitude, the frequency, or the phase of a sinusoidal carrier with frequency much greater than the frequencies present in the message we wish to transmit. View chapter Book 2015, Signals and Systems Using MATLAB (Second Edition)Luis Chaparro Chapter ...
To have convincing results, we use the LDPC coding framework from Matlab toolbox where the LDPC coding follows the digital video broadcast (DVB) standard. The coding bit sequence has 64,800 bits and the number of information bits and parity bits are determined by a coding rate. In this ...
