Abstract

Time Division Duplex (TDD)-based bidirectional digital field pick-up unit (FPU) system is now studying. Hence this digital FPU system shares its frequency band with other wireless systems, digital FPU system should detect and avoid the interference from other systems which signal format is unknown. We studied the spectrum sensing scheme using the received power within preamble signals of FPU system. From the results of the baseband link-level computer simulation, it was confirmed that the proposed scheme achieved an excellent performance of the interference detection.
