A Lab development for real time communication systems with PCsCommunication system classes have been traditionally taught with a lecture-only format.However, the proliferation of new concepts and algorithms in communication systems makes itincreasingly hard for students to master them only through mathematical derivations.Furthermore, without a hands-on demonstration of how the algorithm is used in real-lifeapplications, students without strong mathematical skills can become frustrated and generate aretention problem in EET/CET/EE programs. To overcome this problem, the theory taught inlecture has been complemented with laboratory experiments and class projects. However, manytraditional communication systems’ laboratory experiments are related to various hardware andsoftware, many of which are not easily available outside of the lab environment. In this paper,we introduce a lab that allows students to experience real-time communication systems with aPC and the ubiquitous MATLAB package and, thus, can be done in the comfort of home. Thelab allows the verification through experimentation of various communication system conceptsin real time, processing signals obtained through the PC’s sound card from input devices such asmicrophones, iPods, etc. This paper shows that transmitter/receiver models can be set up in realtime with PCs. Further, it is demonstrated that this laboratory experiment can be extended tomany other labs and/or projects that require real-time processing with the plain use of a personalcomputer.
