WebApr 6, 2006 · Time-reversal space-time coding for doubly-selective channels Abstract: We consider the transmission of space-time block codes (STBC) over doubly-selective channels, which are encountered in highly mobile environments or high-frequency (HF) … WebSep 27, 2016 · A time-reversal symmetry is a transformation T acting on solutions so that. ( T q) ( − t) = T ( q ( t)) holds for all initial conditions; it is not the map t ↦ − t. The above equation means the following: on the left side you evolve the trajectory associated to the initial condition T q 0 backwards in time.
