Description
Summary:Time Reversal (TR) has been identified as a promising technique for green communications thanks to its focusing properties and it has been shown that Equal Gain Transmission (EGT) has similar focusing properties. TR and EGT are perfectly suited to millimeter (mm)-waves band as their performance increases with the transmission bandwidth size and can therefore be applied to IEEE 802.11 amendment ad to perform highly energy-efficient multi-gigabit transmissions. This paper studies TR and EGT application to IEEE 802.11 directional multi-gigabit orthogonal frequency-division multiplexing physical layer (PHY). Efficiency is demonstrated with the help of a channel propagation analysis and bit error rate performance of different line of sight and non-line of sight propagation scenarios and single-input single-output and multiple-input single-output configurations.
