Transmission path identification based on radio channel diversity

机译:基于无线信道分集的传输路径识别

摘要

Various embodiments of the present invention generally relate to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques that use time diversity (eg, different multipaths on the same antenna) to achieve consistency from the same transmitting node. For example, instead of simultaneously starting outgoing transmissions (eg, power signals), various embodiments may initiate outgoing signals from various antennas at stagger timing, which is the inverse of the arrival time of the incoming signal. As a result of staggering the initiation of the outgoing signal, the signal will arrive at the destination at about the same time despite traveling through different paths with different propagation delays.
