This paper presents a novel Software Defined Radio (SDR) architecture for the design of a high-precision positioning system to be used in medical applications. The proposed architecture is composed of a single mobile transmitter and four fixed receivers using a non-coherent demodulation scheme. The transmitted signal consists of a 100 MHZ 64-length OFDM symbol representing the coefficients of a Frank-Zadoff-Chu (FCZ) sequence. The proposed design has been validated in presence of severe multipath interferences. The accuracy achieved in evaluating the position of the target is always within 1.2 cm with a mean error of 6 mm and a standard deviation of 2.2 mm.
