Abstract
A power saving receiver has a controller which is operative to remove power from the receiver when a threshold is exceeded during reception of a packet. The threshold level is formed by comparison of any of: signal energy of unoccupied subcarriers less the signal energy in occupied subcarriers; signal energy in a first range of occupied subcarriers compared to signal energy in a different range of occupied subcarriers; error vector magnitude from a first set of subcarriers to a second set of subcarriers in a different spectral region of the channel; cyclic prefix cross-correlation, or common phase error increase.
