This time reversal operation can be viewed as a mirror of the original phase space on the momentum, and since energy is not changed in time reversal operation (linear time translation), we haveH^(q,p)=H(q,−p), thus if a trajectory(q(t),p(t))is a solution of the Hamiltonian dy...
The author discusses the use of a receiver with a time-reversal structure for improving the performance of a low-complexity decision-feedback equalizer (DFE) in slowly fading dispersive indoor radio environments. Time-reversal operation is done by storing each block of received signal samples in a...

We demonstrate that this emerging anti-unitarity predicates that the universal time reversal operation does not spontaneously appear in nature. To make the time reversal possible, one would need a supersystem manipulating the quantum system in question. In most of the cases, such a supersystem ...
Time-reversal operation on backscattered echo (from Forward probing) and TR probing were execute consecutively after Forward Probing an individual SAR platform position. Results for the three point scatterer, located at the different depth and at the different position along synthetic aperture, are ...
The meaning of TIME REVERSAL is a formal operation in mathematical physics that reverses the order in which a sequence of events occurs.
Time-reversal processing also permits choice of any temporal window to be time-reversed, allowing operation in an iterative mode. In multi-target media, such a process converges on the most reflective target. In the case of an extended target, automatic resonances can be achieved. Applications ...
Firstly, we perform a reversal operation on 𝑦(𝑡)y(t) in the time domain. Secondly, to ensure that the energy between 𝑠(𝑡)s(t) of the forward period and 𝑠′(𝑡)s′(t) of the backward period is equal, the energy normalization term is calculated. Finally, through the ...
