Abstract
This paper extends the previous proposition of Precoded Subcarrier Nulling (PSUN), a novel orthogonal frequency division multiplexing (OFDM) transmission scheme for operation in the 3.5 GHz Band, to consideration of imperfect sensing of radar pulse parameters. We take into consideration existence of Environmental Sensing Capability (ESC), a sensing functionality of the 3.5 GHz Band coexistence architecture. We provide an analysis framework where variables representing impacts of imperfect sensing on an OFDM system are generalized. The framework demonstrates impacts of sensing errors by an ESC and parameter changes by a radar. Our results show that PSUN still is effective in suppressing inter-carrier interference (ICI) even with imperfect sensing.
