In this paper, we present simulation exercises with emphasis on learning to build blocks and subsystems and integrating them into a communication system. Through these exercises, the students learn to build communication subsystems from the basic building blocks that are available in the SIMULINK library. The subsystems are built as close approximation of instruments and hardware modules that are available in a laboratory. Data sources have included programmable jitter. Students make their own library of these subsystems and use them to build large and complex communication systems such as the BFSK, BPSK, QPSK and QAM systems. Exercises include finding frequency spectrum of analog signals and digital data streams, analog- to-digital conversion, digital modulation systems, phase lock loop operation and frequency synthesizer, coding and decoding processes.

I. Introduction

Simulation exercises help greatly in learning of complicated systems which otherwise will be difficult to build in a two or three-hour lab class period. Equivalent hardware exercises would require extensive set-up time and frustrating trouble-shooting experience. Moreover, the hardware components and equipments are expensive and have long acquisition times in an educational setup.

The communication circuits and subsystems are now available as merchant integrated circuits. Engineers and technologists in the modern telecommunication industry configure systems and build them from subsystems and ICs. The subsystems, even though procured from multiple vendors, use standard interfaces to enable trouble-free interfacing. The uppermost design issues before the engineers now are interfacing of subsystems. MATLAB SIMULINK [1] is popular software for developing educational exercises. However, several of these exercises use blocks that perform mathematical operations [2]. These blocks have little resemblances to the equipments and hardware units, which are used in practice. In this paper, we present the simulation exercises that enable the students to build equipment-like blocks and construct complete communication systems and simulate, observe and understand parametric variations.
