Wireless telecommunication systems have increased at an enormous rate over the past few years. Various modulation techniques have been developed with the objective of improving the quality of service. The main goal of these techniques is to improve the bandwidth and power efficiency while keeping the bit error rate (BER) at acceptable levels.1,2,3 The complexity of these systems along with the high frequency of transmission makes it difficult to develop undergraduate laboratories that can be used to teach the needed concepts. Some teaching systems exist but cannot be easily tied to existing commercial systems. Equipment to test and characterize these new commercial communication systems is complex and expensive. To overcome some of these problems, student projects can be developed using a PC-based system for simulation and application. The PC-based system used in this example is LabVIEW, or Laboratory Virtual Instrument Engineering Workbench, a graphical programming language developed by National Instruments. It is used extensively for data acquisition, instrument control and analysis.4 In this example, a communications system was developed through student projects and a coop experience. This system has the capability of simulating a receiver or transmitter using a number of different modern communication techniques. Although the system operates at a much lower frequency than modern communication systems, it can measure a number of parameters of the receiver or transmitter. A number of modulation schemes are available in the system including phase shift keying (PSK), frequency shift keying (FSK), quadrature amplitude modulation (QAM) and a generic I and Q modulation scheme. A number of different variations of PSK and FSK are also included.
