On-line laboratory for communication systems using J-DSP

The J-DSP editor was developed at Arizona State University (ASU) to enable students to conduct on-line simulations and experiments in digital signal processing and related subjects. In this paper, we describe a series of J-DSP communications functions and laboratory exercises that have been developed to support the laboratory portion of the ASU communications elective, EEE455. The functionality developed covers both analog and digital communications. The J-DSP communications laboratories include descriptions of relevant J-DSP functions, lab exercises illustrating the key concepts, and a short quiz that captures the main points of the assignment. The J-DSP communication labs have been assigned in EEE 455 and assessment results have been compiled. The students responded to specific questions on the labs and the J-DSP environment in general. Assessment results indicate that the majority of the students responded that the new JDSP functionality and the associated lab exercises complemented well the theory covered in class and helped them develop intuition on the communications concepts covered in these labs.
