Simulation Of Flat Fading Using MATLAB For Classroom Instruction* Gayatri S. Prabhu and P. Mohana Shankar Department of Electrical and Computer Engineering Drexel University 3141 Chestnut Street Philadelphia, PA 19104 Abstract An approach to demonstrate flat fading in communication systems is presented here, wherein the basic concepts are reinforced by means of a series of MATLAB simulations. Following a brief introduction to fading in general, models for flat fading are developed and simulated using MATLAB. The concept of outage is also demonstrated using MATLAB. We suggest that the use of MATLAB exercises will assist the students in gaining a better understanding of the various nuances of flat fading. * This work was supported, in part, by the Gateway Engineering Education Coalition under NSF Grant # EEC 9727413. 1 I. INTRODUCTION Wireless communications is one of the fastest growing areas in Electrical Engineering. Because of this, courses in wireless communications are being offered as a part of the electrical engineering curriculum at the undergraduate and graduate level. With the incorporation of computers in the curriculum [1], [2], it has become much easier to bring some of the concepts of this new and exciting field of wireless communications into the classrooms. MATLAB is extensively being used in colleges and universities to accomplish this integration of computers and curriculum. In this paper, a MATLAB based approach is proposed and implemented to demonstrate the concept of fading, one of the impo
