“…In ; Kyritsi, Papanicolaou, Eggers & Oprea (2004), using the data from a fixed wireless 8 × 1 MISO measurement, a delay compression by a factor of 3 was shown to be possible. In Qiu et al (2006), using the experimental results, temporal focusing and an increase in collected energy with the number of antennas in MISO-TR systems is verified. Also, the reciprocity of realistic channels is demonstrated with the help of MISO-TR.…”

“…Since TR can make full use of multi-path propagation and also requires no complicated channel processing and equalization, it was later verified and tested in wireless radio communication systems. Experimental validations of TR technique with EM waves have been conducted in [24], [39]- [45], including the demonstration of spatial and temporal focusing properties [24], [39]- [45] and channel reciprocity [24], [41]. The feasibility of applying TR technique into ultra-wideband (UWB) communications has been studied in [46]- [48] with the focus on the bit error rate (BER) performance through simulation.…”

Abstract-In this paper, we present an overview of the timereversal (TR) wireless paradigm for green Internet of Things (IoT). It is shown that the TR technique is a promising technique that focuses signal waves in both time and space domains. The unique asymmetric architecture significantly reduces the cost of the terminal devices, the total number of which is expected to be very large for IoT. The focusing effect of the TR technique can harvest the energy of all the multi-paths at the receiver, which improves the energy efficiency of the wireless transmission and thus the battery life of terminal devices in IoT. Facilitated by the high-resolution spatial focusing, the TR division multiple access scheme leverages the uniqueness of the multi-path profiles in the rich-scattering environment and maps them into location-specific signatures, so that spatial multiplexing can be achieved for multiple users operating on the same spectrum. In addition, the TR system can easily support heterogeneous terminal devices by providing various quality-of-service (QoS) options through adjusting the waveform and rate backoff factor. Finally, the unique location-specific signature in TR system can provide additional physical-layer security and thus can enhance the privacy and security of customers in IoT. All the advantages show that the TR technique is a promising paradigm for IoT.Index Terms-Internet of Things (IoT), spatial focusing, temporal focusing, time reversal (TR), time-reversal division multiple access (TRDMA).

“…[10] proposed an MMSE-TR equalizer in UWB communications and investigated the benefit of temporal focusing. The authors in [11,12] evaluated the applicability of multi-user TR-UWB communication in improving the multi-user system capacity and communication range. Combined with TR technique, the Impulse Radio-UWB (IR-UWB) systems have no need to use the Rake receiver to obtain good demodulation performance.…”
