Using smartphones as mobile implementation platforms for applied digital signal processing courses

This paper presents a newly developed laboratory paradigm for teaching applied or real-time digital signal processing courses. It involves the utilization of smartphones to implement digital signal processing algorithms in real-time using ARM processors of smartphones. Representative laboratory experiments together with an application project running on smartphones as apps are discussed in the paper. It is shown that such a paradigm provides a cost-free and a truly mobile laboratory environment for students to learn implementation aspects of signal processing algorithms.
