A Review of Some Important Math, Stats, and Systems
My intention in writing this chapter is to give a quick review of key mathematical, statistical, and engineering concepts which we’ll use in our study of telecommunications. I basically provide a brief review of random variables and random processes, and then talk in passing about the Fourier transform and linear time invariant (LTI) systems.
