(事前公開アブストラクト) Authors are developing the multiple subcarrier multiple access (MSMA) which enables concurrent sensor data streaming. Delay due to software defined radio (SDR) processing occurs when MSMA signal is output. Estimation of processing delay is indispensable for sensing requiring synchronization of input signal and output signal. Authors developed estimation system of SDR processing delay in multi subcarrier multiple access. In this presentation we report calibration method and its estimation result.
