The design, implementation and measurement of a real-time modem with chirp spread spectrum (CSS) modulation on a software-defined radio (SDR) platform are presented. The symbol, the frame, the synchronization and the decision rule are derived from the initial requirements. The receiver acquires the frame in the stream and decodes it at its rate. Packet error rate (PER) and sensitivity were obtained experimentally over the air and over cable with USRP frontends.
