The author, Floyd M. Gardner an influential expert in the area of PLLs, has presented a good reference book that encompasses all the theoretical and mathematical concepts for the phase…

Tapped-delay line filters (basically FIR filters) are best to simulate multiple echoes originating from same source. Hence they can be used to model multipath scenarios. Choose frequency-flat or frequency selective: If the…

Generation of random variables with required probability distribution characteristic is of paramount importance in simulating a communication system. Here, I will demonstrate how we can generate a simple random variable, estimate &…
