Abstract
Linear FM (Chirp) signals have the merits of constant envelope and insusceptibility to significant carrier frequency offset which particularly suit for low-power low-rate communications. However, the fully digital implementation of the matched filter for the chirp signals is not economically feasible. A low data-rate communication technique using linear step frequency modulated (LSFM) signal was thus proposed which exhibits a complexity reduction in the matched filter implementation with an acceptable performance loss compared to the chirp signals. This paper presents an implementation of such an LSFM transceiver on a realistic commercially available software-defined radio (SDR) platform. Specific system parameters in the LSFM are designed for a furthermore complexity reduction. Implementation cost and experimental results are presented.
