Pass FSK and QPSK signals through a Rayleigh multipath fading channel. Change the signal bandwidths to observe the impact of the fading channel on the FSK spectrum and the QPSK
Apply various RF impairments to a QAM signal. Observe the effects by using constellation diagrams, time-varying error vector magnitude (EVM) plots, and spectrum plots. Estimate the
Plots the power of a faded signal versus sample number. It illustrates the syntax of creating and calling a comm.RayleighChannel fading channel object and the state retention of the channel
Illustrates how to change the default Jakes Doppler spectrum of a constructed Rayleigh channel object to a flat Doppler spectrum:
Change the default Jakes Doppler spectrum of a constructed Rician channel object to a Gaussian Doppler spectrum with normalized standard deviation of 0.3, and subsequently display the
Creates a frequency-flat Rayleigh fading channel object and calls it to process a DBPSK signal consisting of a single vector. Bit error rate is computed for different values of the
Filters input dat through a Rayliegh fading channel within a for loop. It uses the small data sets from successive iterations to create an animated effect. The Rayleigh fading channel has two
Illustrates how to change the default Jakes Doppler spectrum of a constructed three-path Rayleigh channel object to a cell array of different Doppler spectra, and then change the
Set the bit energy to noise density ratio (Eb/No) for communication links employing channel coding.
The syntax for viewing and changing Doppler object properties is the same as for the case of channel objects (see Displaying and Changing Object Properties ).
The value of a channel object's ChannelFilterDelay property is the number of samples by which the output of the channel lags the input. If you compare the input and output data sets directly,
