TIME DISPERSION MEASUREMENTS IN RADIO COMMUNICATIONS SYSTEMS

摘要

Time dispersion of a signal that has been received from a channel is measured by utilizing metrics to determine the energy inside an equalizer window and outside of the equalizer window. In one embodiment, the estimate of the energy outside the window is a difference between residual interference estimates. In another embodiment, the estimate of the energy outside the window is a difference between residual impulse response power estimates.
