Green Wireless Communications: A Time-Reversal Paradigm
TL;DR: This paper shows that the time-reversal signal transmission is an ideal paradigm for green wireless communications because of its inherent nature to fully harvest energy from the surrounding environment by exploiting the multi-path propagation to re-collect all the signal energy that would have otherwise been lost in most existing communication paradigms.

TL;DR: An overview of the time-reversal (TR) wireless paradigm for green Internet of Things shows that the TR technique is a promising technique that focuses signal waves in both time and space domains and can enhance the privacy and security of customers in IoT.
Time-Reversal Division Multiple Access over Multi-Path Channels
TL;DR: It is shown in both analytical and simulation results that desirable properties and satisfying performances can be achieved in the proposed TRDMA multi-user downlink system, which makesTRDMA a promising candidate for future energy-efficient low-complexity broadband wireless communications.
Time-Reversal Wideband Communications
TL;DR: This letter finds that when the bandwidth is large enough, time-reversal system can achieve much higher achievable rate than OFDM system and is a desired solution to low complexity high throughput wideband communications when more bandwidth is available.
