The power delay profile (PDP) of the single antenna full-duplex self-interference channel (SIC) is studied in the indoor environments in this paper. We perform the measurements at the center frequency of 2.4 GHz with 100 MHz bandwidth. The PDP can be decomposed into three components: leakage path (LP), antenna reflection path (ARP), and space multipath (SMP). Furthermore, we get the model of the profiles of the leakage path and the antenna reflection path. The space multipath can be modeled as power-law decay plus a random variable with lognormal statistics.
