Stochastic Processes Introductory Lecture Sajjad Hussain

Why should I study this course… [1] Signal Processing ???

Why should I study this course… [2] Computer Memories To make the system reliable we store k+l bits instead of k original bits At least how many bits out of k+l bits read correctly would suffice the correct data reading Binomial Random Variable shall provide the answer. Optical Communication Systems Photo detector converts light into electrical energy. Photoelectrons produced are well modeled by Poisson Random Variable.

Why should I study this course…[3] Wireless Communications Thermal noise modeled as Gaussian Random Variable Rayleigh, Rician, Chi-squared distributions to model different wireless channels Computer Network Traffic LANs, WANs, www traffic can be linked to Markov Chains Studies have produced surprising insights into buffer size, congestion control, connection duration prediction etc. BUT…
