In the era of Internet of things (IoT), the demand for wireless network (NW) that can accommodate the wide range of terminals at low cost is increasing. For this reason, the developments of low-power wide-area (LPWA) network is actively underway. In

Time Division Duplex (TDD)-based bidirectional digital field pick-up unit (FPU) system is now being studied. This new digital FPU system shares its frequency band with other wireless systems. Therefore, digital FPU system should detect and avoid the

By establishing a guard interval, the OFDM method shows excellent characteristics in a multipath environment. However, if the delay spreading exceeds that guard interval, intersymbol interference occurs. In this paper, we propose a method of extendin

A very simple but general scheme for calculating irreducible bit error rate (BER) (namely, BER floor) due to inter-symbol interference (ISI) in frequency-selective Nakagami-Rice fading environments has been developed. The scheme, to which we call the
