I have always been fascinated with mobile app development. Over the last couple of years in college, I made a few attempts to get started with Android applications. I watched tutorial series, reading blogs, attending introductory workshops. Nope. Nothing seemed to stick. What was wrong?
This year I am leading a senior design team in developing a software defined radio that can talk with a satellite that Vanderbilt just launched. Compared to a normal radio, an SDR has most of the signal processing functions implemented virtually. This means that it can change its operation on the fly. An interesting application of SDRs is cognitive radio: that is, radios communicating with other radios in their vicinity and adjusting their frequencies to maximize their use of the bandwidth.
