Fading channel – complex baseband equivalent models

Keyfocus: Fading channel models for simulation. Learn how fading channels can be modeled as FIR filters for simplified modulation & detection. Rayleigh/Rician fading. Introduction A fading channel is a wireless communication channel in which the quality of the signal fluctuates over time due to changes in the transmission environment. These changes can be caused by … Read more

Random Variables, CDF and PDF

Random Variable: A random variable is a mapping from sample space $latex \Omega\$ to a set of real numbers. What does this mean ? Lets take the usual evergreen example of “flipping a coin”. In a “coin-flipping” experiment, the outcome is not known prior to the experiment, that is we cannot predict it with certainty … Read more
