TL;DR: Two smart threshold setting methods are proposed, called dynamic threshold selection (DTS) and realtime threshold setting (RTTS), respectively, to overcome the NU produced by hardware system noise in spectrum sensing.

TL;DR: In this article, the authors proposed a radio communication method for eliminating blockage effect due to collision of a large number of pieces of data, which includes the steps of: determining the connection available number of lower-level terminals relative to an upper-level terminal, connecting the lower level terminals and the upper level terminals on the basis of the determined connection available numbers, transmitting first data from the connected lower-layer terminals to the upperlevel terminal; generating combination data by combining the first data received by the upper layer terminals and second data which the upper-layer terminal should transmit; and

TL;DR: A partial (channel) bandwidth based feature detection (PB-FD) method is proposed, which not only exploits identical features of DTV standards, namely the DVB-T and ISDB-T, to produce high process gain in detection, but also significantly mitigates the ACI produced by transmission power leakage.

TL;DR: In this paper, a 60 GHz radio-over-fiber (RoF) network using an electroabsorption modulator (EAM) is presented, where a photonic frequency upconversion technique that utilizes the wavelength conversion process in the EAM is adopted for seamless integration of optical and wireless networks.

TL;DR: An exact expression of error rate is developed for maximal ratio combining (MRC) in an independent but not necessarily identically distributed frequency selective Nakagami fading channel taking into account inter-symbol, co-channel and adjacent channel interferences (ISI, CCI and ACI respectively).
