This paper implements an OFDM based system for joint communications and sensing. OFDM traditionally is used for passing modulated information bits in a multi-path channel. Prior to decoding the information bits, channel state information (CSI) is extracted from multiple sub-carriers in OFDM frames. The GNU based OFDM sensing performance is compared with our prior GNU based CW radar implementation. The results shows distinct but insightful sensing performance from OFDM based and radar based implementation. The comparison study highlights the advantages and disadvantages of OFDM based human physiological signal measurement.
