Model channel and RF impairment characteristics.
This example shows how to set the bit energy to noise density ratio (Eb/No) for communication links employing channel coding.
Two links perform error control coding on a signal that has passed through an impairment channel.
Defining a fading channel object and applying it to a signal.
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 constellation.
